Tom V, You might be right but the way you come across with your view makes you just another arrogant ass with no friends and a lot of time to belittle people. Go play with your paper dolls and leave Sullivan alone. Jerk!! Ron H
Thanks - this was one of the first videos I did, and I think I got a little better as time went on. I'm still trying to find my real style. Hope it helped.
Daniel thank you for this video. I'm just getting started in electrical and I've been struggling but this really helped me understand the basic principles. You are an excellent teacher.
As a fellow teacher (though in the humanities) I want to thank you for the simplicity with which you connect what could be abstract and confusing with the everyday and implicityly understood. That is great teaching!
I'm dumb I'm sad This made me happy I passed my test For the 1st time In a long time I didn't only pass I got 98 The question I failed at Was What are volts
Best video I've seen yet to explain this stuff. This guy has a great method of teaching - you have to break it down to simple terms that dummies like me understand :)
Your analogies are ingenious! Simple truth is profound, and so effective! Great job, Sir! And by the way, only a genius could think to sync a high speed video with a lecture spoken at natural or normal rate and make it work. A lot packed into a little space and time, yet, so simplified so as to understand it and retain it. Well done, Sir. Great video!
I have never subscribed to a youtube channel until seeing this video. What a great basic instruction into these concepts. Perfect blend of information, humor, and a combination of visual and audible instruction. I'm getting pumped about electricity!
Thank you so much for this. I've watched other people try to explain this, but they didn't explain concepts like you. Instead of regurgitating definitions to me, I feel like I actually understand what those definitions mean.
pharmer11 yeah, he is such a great teacher that I wanna open his head and steal his brains. Imagine what it is like to have many stolen brains belonging to geniuses and what we could do with them. =)
So you say. Yet you offer nothing in the way of support. In fact, it isn't even clear you understand Dan, let alone the material he's conveying. I'd love to see something in the way knowledge coming from your direction instead of blanket, uninformed, denial. Maybe you feel he's wrong but can't articulate it. Well then, give it try. Let's see your refutation, point for point.
First off, your attempt to inflate yourself by referring to me as LB is silly. As to your "Here you go," No, not really. You post a link, (enjoyable presentation BTW) along with your assumption that there is a fundamental difference between the respective explanations of the concept of voltage. Both explanations must employ metaphor in order to give the viewer a means to understand the phenomena of voltage. In addition to these, there are many others that work too. Anyway, as far as your point to point refutation, you would still need to articulate the differences and how those differences establish your assertion. That is, if you wish to claim that you've provided a point for point refutation.
This gets right to it. The problem seems to be that you don't know enough about what "understanding' is, to make such a claim. With a deep understanding of the concept of voltage, you'd easily be able to step in and clarify, support, and advance the understanding of others where it was needed in this thread. Instead, you simply shout assertions with the apparent confidence that those assertions are supported by the truth. But the trouble with that is, while voltage is well-understood, it is only well-understood by the use of a whole mess of metaphors. All your huff and puff amounts to is a preference over which metaphors are used. You're too caught up in a game to show how great your understanding is. Open up a bit. You can thank me later.
Loving your videos Dan. I am a creative type with no former exposure or experience in this arena.. Needing to learn for business purposes. Your examples are just awesome. Love the slinky VOTAGE video, too. Thanks for taking the time to do these.
I just got 2 books on basic electronics and they both neglected to explain the basic concepts as thoroughly and as well as your presentation. This is a big help. Thanks!
I feel this dude may really excel at actually teaching electricity to people! With such an important topic it's great to see an improvement in spreading the understanding of this subject! I feel there's too many schools of thought that teach electricity the same way it was taught like 100 years ago! I think you should make some more videos on electrical concepts that you may be able to explain in your own special style that you got here! Anyways, nice work...And thanks!
> I feel this dude may really excel at actually teaching electricity to people! I'm sure you feel a lot of things. But what you feel is not inherently true.
You explained everything very clearly. Thank you for the great video. I'm just beginning to learn this. It really helps to be able to visualize how it works.
This video was so much better explained than most other people. Either people would throw equations at you or talk about some super soaker garbage. You explained it perfectly and broke it down to a simple level.
Daniel. Thank you for your video. I'm a late 40's guy trying to learn what I can about electricity and your illustrations are wonderful. The story telling method of teaching works best for me. Keep it up!
I am in school for Audio and Electronic Engineering and have been taking Electronics I for the past 10 weeks. You have explained this in such a amazing way. I have arguably the best electronic teacher in the Pacific Northwest, but I think I benefit tremendously from this type of instruction. Thank you for your time!!
Absolutely the best explanation for someone like myself who wants basic fundamentals. I finally get it. Thank you for not showing off and actually teaching.
Your conclusion was the best. I could never deduce ohms law as a math equation, only as a concept, and yet it’s taught with insistence as a math equation. You are a real professor. Thank you!
You haven't heard my explanation of time travel through the exploitation of the tunneling effect of capacitive reactance in super-condensers, using flux variation due to high amperage field distortion in four dimensions. It's pretty good too...
Daniel Sullivan Wait a minute... tunneling effect of capacitive reactance, flux variation, high amp field distortion in 4D....... FLUX CAPACITOR! Did you hit your head on a toilet seat recently? JK. You did a great job on this. I recently started doing some similar vids but yours is much more concise. Good presentation. I have a lot of room for improvement. Cheers!
Most useful intuitive description I've heard or read yet. Brilliant delivery! Thanks!! I still contend that true intelligence should not be measured by the ability to understand complex things, but instead the ability to make complex things simple. More should follow your example! Cheers!
There is one little flaw in this, which is that the battery has to have a difference in potential on the plus and minus side in order for the electrons to flow. The picture does not include this. Actually nothing would happen if the battery was constructed like that. Still like the analogy very much though! Thanks for your contribution!
+Andreas Toft Nagel Yep - you're right. However, the battery and wiring are filled with electrons, each with a (-) charge. It's a little tough to draw pressure, because voltage is a state of energy, not a quantity... And, this is the "crawl" part of "crawl, walk, run" process of learning about electricity.
> because voltage is a state of energy, not a quantity... That is simultaneously wrong and ludicrous. Voltage is without a doubt a quantity. Go look at a battery. Volts. 9 volts is a quantity. Good god the degree of your ignorance is well beyond astounding.
> because voltage is a state of energy, not a quantity You have apparently not payed attention to your batteries. They have voltages like 9 or 1.5. That's a quantity. Numbers. Quantities. That's what quantities are.
My electricity teacher always used water as an analogy for electricity as in amount of water, speed and things in the way. I thinks I learned more from this than my 2 semesters with him. Thank you
Gerard Vaughan You do realize this video isn't teaching or illustrating what a battery is, right? You understand I'm trying to present the vague concept of voltage that isn't typically taught in tech schools. right.? You realize your opening insult pretty much destroys your credibility, right? Are you a teacher or do you just fantasize about being respected? The irony is that everything you wrote is correct - and even though you tried to insult me, I'm humble and confident enough to tell you that. Perhaps if you weren't as pissy you'd be a pretty good teacher after all...
I'm not quick at understanding these concepts, but you breaking it down gives me hope. You did a great job explaining and I will repeat this and watch again with my kids so they understand. Thank you!
See - I told you my job is to have more faith in you - than you. You can do this stuff - all you need to do is have confidence, focus on the concepts, and don't be afraid to ask a LOT of questions. Once you learn and understand the basic concepts everything else is easy. Ohm's Law can never fail. Happy Holidays. DS
I've always been a curious and interested person in electricity but I could never figure out what the difference between volts, amps, watts, and ohms was. But this video cleared it up a tremendous amount. Thank you!
It is very sad that for 5 years i wasn't able to understand this concept well and you make it clear with in 8 minutes. I would be very happy if all colleges and universities considered wonderful teachers like you to establish the students through their senior studies.
Im electrical first year student. yesterday one of my teacher ask what is voltage & current? nobody have no idea about it .but now i got it. thank you very much
Motor or resistor would be a 'load'. The amperage depends on the load value in ohms. If there were no motor or resistor, it would be a short circuit, meaning infinite amperage, on paper.
This is the best ans easiest explanation that I've found! I have taken basic electrical and have struggled constantly because of all the math and letters. Thank you for making this!
Thank you for the very easy to understand explanation! Ohms law is something that has shamefully eluded me in my career as an AV tech, now I have to take my OSHA30 and am to be tested on it! I feel much more confident I can do it now. :)
The explanation was very good except that I got confused at 5:42 in the video. After you close the switch, the high pressure electrons jump out of the box (where they are under higher pressure) on to the wire which has presumably atoms at lower pressure (nicely spaced out). But should they not end up at a positive terminal (where the pressure is much lesser than the negative terminal). Your video seems to connect box of high pressure electrons back to itself. Unless the flow is to a lower pressure box the currently should not flow continuously,
yeah.. that's what stumped me also. Normally, the electrons wouldn't flow at all in his setting because there is no difference in pressure. He should have divided the battery in 2, put a high density electron area and a low density area. The current flow should be from high to low density area until they balance eachother out and push against eachother equally,
You have both correctly identified the fundamentally wrong concept this video is based on. Electrons do not flow out both terminals of a battery. If they did, there would be no point of '+' and '-' terminals and you could jump-start a car connecting a battery any old which way (which is what Daniel's students would do which is why I won't let them near my car .... ever).
i agree. I think the video is splendid accept for that part. There it seems to be just wrong. The electrons travel through the wire, doing work etc. BECAUSE they want to go/are attracted to the positive charges in the other side of the battery. Of course this model also is a simplification, since there are chemical reactions going on at both sides of the battery, the sum which leads to a flow of electrons. But that is overcomeable. But the depiction at 5.42 is not. In the video there is no reason for the electrons to flow trough the circuitry, only to leave the battery.
Really a very helpful video. Thank you Mr Sullivan for making this video and sharing with everyone. After checking some reference books and asking some experts, nothing is clearer than what you shared. Thank you and the Lord blesses you!
Lool Thanks!! Thanks to you, I think I may have done good on the exam. Most of the electricity section was based on Volts Ohms and Amps, and I wasn't in class for those (I was doing our Christmas Show)
coolkidsahib I'm sure the atmosphere was electric. Hopefully the cast was a great group of high voltage people. You need to stay current in class. Don't put up too much resistance to asking questions... (See what I did there?)
I'm glad you think that my videos are frequented by individuals with adequate education and background to understand your descriptions and explanations, but it's important to remember that I teach mechanics ------ the guys who sat in the back of class and were culturally ostracized. If we were as stupid as our teachers and counselors thought, nothing would run. I've said it a million times - crawl, walk, run... If you (and many others) are as intelligent as your posts hope to prove, teach... But - crawl, walk, run. BTW - can you guys weld, wire a building, build a house, pour concrete, do masonry, operate a lathe or mill? Just curious. Occupation doesn't dictate intellect. The man makes the job, not vice versa.
Tom V. There you go being an arrogant ass again. Why do you have to be so bitter. If you don't like his teaching method shut the heck up and go away. No one is asking to watch. Jerk!! Ron H
> Tom V What is wrong in the video ? I believe I have made that abundantly clear. Pretty much everything in the original video is either incorrect or misleading to a terrible degree. 1) electrons are not scrunched up in a little box trying to get out. 2) Batteries have terminals. Positive and negative terminals. That is kinda important especially if you are hired to jump-start a car. 3) Pretty much everything else in the original video is wrong. You can use the water analogy as a better guide to basic DC electricity. Go google. Any other questions?
Thank you!! I will be sharing this with my grade 9 students. Not only will it help them but I too and more confident in understanding this concept! Thanks!
That's because the explanation is completely wrong. You would do better checking out a course on Coursera or Khan Academy, or just plain googling around plenty. The concepts here couldn't be more flawed than they are.
Tom Vilot if this is wrong, and you are so adamant to point this out, why not make a video correcting the errors. Nothing worse in this world than a man that won't contribute to his fellow man, yet sits at the table to eat their food.
BUT OHMS LAW IS MEASURED WITH MATH TO GET THE ACCURATE LEVELS.... SO WHY IS IT NOT AN EQUATION. ? IF NOT YOU WOULD NOT KNOW THE NUMBERS YOU NEED TO KNOW THE CIRCUIT. DUH?
I just completed a course from tpc and after the course, you will get a better idea of electricity. I have worked with electrical components and motors for years. After the course, I have a better idea of how it works plus the safety involved. You can't see it and you can't feel it until it's too late. Be cafeful, follow basic rules and you should be okay.
Dan well done. It was clear and understandable. Many years ago I took "Electricity" in high school and never understood the physics part of what you were able to explain in eight minutes.
DOH!!! I’m 58 and I always thought that high tension wires on the poles meant the way they were strung, like in engineering tension and compression of the actual wires, not the stuff inside them. Wow do I feel stupid at the moment but then nobody ever explained what they were, just pointed and said, they are high tension wires, don’t touch or they’ll kill you. Hmmmph. I’m only half way through but had to stop and interject. I’ve known the formulae etc and have used over the years but I’ve never truly understood how electricity worked but now I think I starting to understand and hopefully you will continue to teach me and I will continue to learn from you. I cannot tell you how grateful I am to stumble upon your video on this, the last day before 2020 comes, what a great new way to start a new decade, thank you
> i dont think anyone knows how magnets work.....just saying.....i mean noone knows how they ACTUALLY work It's not that complicated and has been understood for quite some time. Electrons. Atoms. Materials. It's not that hard to follow (unless Daniel is teaching the course, in which case you are completely f&cked). www.livescience.com/38059-magnetism.html www.howmagnetswork.com/ I googled for you. You're welcome.
@@tomv3999 My god you are so incredibly annoying. It's like someone attached a megaphone to a mosquito and let it fly around the comments section for three hours.
I teach this in welding, and it really helps the students understand where the heat is coming from; arc created through resistance, and only works when you're a certain distance away at all times. Air is a great insulator.
lol seeing as ur smarter than my science teacher, i should just stop going to school (.....actually.....everyone is smarter than my science teacher, hes an idiot...proof, you know those vandograph static hair-go-up thingys? he says those creates 200 000 volts. Thats frikin enoght to power my entire school!!!!!!!!))
From one teacher to another you might want to let up on the metaphors. "The electrons are upset and have stress" Relating electrons to a human emotion just confuses people and has nothing to do with what they do. Also you are writing TOO much. is slows the learning process and does NOT help with memorization. Pictures are good but don't spend a lot of time making them really cool, again it slows things down. Watch a couple of Veritasium when he writes and draws Magnetism is a good one. Good luck. Fist up, Fight for Truth.
Thanks, but you watched one of my first videos. I've gotten better over two years, and with respect, from one teacher to another, it's worked for 28 years, so I'll keep at it. However, I do appreciate criticism. Depending upon who and what you teach, you may or may not appreciate that teachers are by far the most critical, and seldom without some ego involved. Not knowing you I can't say, but people either love me or hate me. Most respect me. Feel free to comment, but it would help me more if you watched number 80 too.
Going to have to disagree with you. I thought that the way he presented this was actually pretty refreshing and wish I had a teacher in university that explained ohms law to me like this. If the metaphors in this video actually confused anybody then understanding ohms law and other fundamentals of electricity probably wasn't in the cards for them to begin with.
i paused only to say that you are a very good teacher !!! it is not enough just to know to be a teacher you also need to be able to transfer your knowledge . excellent from me.
Thank you very much. You are the BEST in the business!What great teaching! I AM VERY GRATEFUL...FOR ANYONE WHO WANTS TO UNDERSTAND THESE CONCEPTS , HE IS YOUR BEST BET!!!
Nice job. A good teacher can take a very complex idea and break it down simply so that anyone can understand. You've accomplished this.
No, the explanation is completely wrong.
But what did I expect from someone who is (by his own terms) a douche?
Thanks.
Justify yourself.
google.
Tom V, You might be right but the way you come across with your view makes you just another arrogant ass with no friends and a lot of time to belittle people. Go play with your paper dolls and leave Sullivan alone. Jerk!! Ron H
So you understand this now 💥
That's great 👍
You are the first person to explain these things in a way I can understand! Thank You very much!!!!! YOU ROCK!
Watched an explanation riddled with ads and marketing interruptions for 30 mins.
Then came here, thank you, thank you, thank you.
Thanks - this was one of the first videos I did, and I think I got a little better as time went on. I'm still trying to find my real style. Hope it helped.
Daniel thank you for this video. I'm just getting started in electrical and I've been struggling but this really helped me understand the basic principles. You are an excellent teacher.
Mr. Sullivan, what happened to your website? I'd like to purchase your book. Could you please direct me to one of your vendors?
Hi Dan, Thanks for the great videos-extremely helpful! I am transitioning from electrician, to instructor. So much I don't remember.
As a fellow teacher (though in the humanities) I want to thank you for the simplicity with which you connect what could be abstract and confusing with the everyday and implicityly understood. That is great teaching!
I'm dumb
I'm sad
This made me happy
I passed my test
For the 1st time
In a long time
I didn't only pass
I got
98
The question I failed at
Was
What are volts
A unit that measures electrical pressure.
@@ryanrai6927 volt is named after Alessandro Volta 😊😊😂
I was taught think of a river. Water is voltage, speed of the water is current, water flowing over a surface (riverbed) is the resistance.
Best video I've seen yet to explain this stuff. This guy has a great method of teaching - you have to break it down to simple terms that dummies like me understand :)
I'm glad you guys are liking this. I'm planning to do another one that uses some new examples I've worked out in the past couple of years.
Daniel Sullivan Sounds good! You have a great teaching style - something that is pretty rare if you have a look around youtube for similar videos...
Your analogies are ingenious! Simple truth is profound, and so effective! Great job, Sir! And by the way, only a genius could think to sync a high speed video with a lecture spoken at natural or normal rate and make it work. A lot packed into a little space and time, yet, so simplified so as to understand it and retain it. Well done, Sir. Great video!
I agree. The voice-over narration synchronized with a high speed drawings was brilliant. His voice is equally soothing and makes for a great teaching.
Sir, you are doing the lords work. Watching this is the first time any electrical current anything has ever made sense! Thanks you!
This is the best explanation of these concepts I have ever heard.
An eight minutes video have taught me better than a school I've spent thousand of dollars on. Thank you sir. I need to buy your book
i survived college and never had it explained this way
big thanks
I have never subscribed to a youtube channel until seeing this video. What a great basic instruction into these concepts. Perfect blend of information, humor, and a combination of visual and audible instruction. I'm getting pumped about electricity!
Yeah, but this video is 99.99% wrong. Clearly, you did not make it through high school physics (nor did Daniel).
Thank you so much, I have a science test tomorrow and this has really helped a lot!!! You are a great teacher!!!!!!!!!!!!!!!!!!!!!!!
This is a great video for anyone wanting to understand how electricity works! Very well explained, nicely done Mr. Sullivan.
One of the best examples I've ever seen! Great explanation!!!

I wish i had a teacher like you in my childhood ..superb explanation ..Excellent Teaching
Skills
That, by far, has been the simplest description and explanation of Ohm's Law that I have ever heard or read. Thank you, sir.
You sir are a fantastic teacher. That was the best explination I have come accross.I finally understand what voltage, amps and current are. Thank you

That is simultaneously wrong and ludicrous.
Voltage is without a doubt a quantity. Go look at a battery. Volts. 9 volts is a quantity.
Good god the degree of your ignorance is well beyond astounding.

You have apparently not payed attention to your batteries. They have voltages like 9 or 1.5. That's a quantity.
Numbers.

No. He didn't.
I am blown away by the clarity and elegance of Daniel's explanation.
"E" is Electromotive Force, and "I" is Intensity... You got me...
This is hands down the clearest explanation of these concepts and their relationship to each other. Thank you!
Simple and clear, one of the best I saw thank you

I've always been a curious and interested person in electricity but I could never figure out what the difference between volts, amps, watts, and ohms was. But this video cleared it up a tremendous amount. Thank you!
Mr Daniel, This is freaking AMAZING!!!!
That's because electricity is freaking AWESOME. Stick with it - learn the mechanical Ohm's Law (V & Ω *MAKE* A)
> Mr Daniel, This is freaking AMAZING!!!!
Yes! Because it is amazingly incorrect.
It is very sad that for 5 years i wasn't able to understand this concept well and you make it clear with in 8 minutes. I would be very happy if all colleges and universities considered wonderful teachers like you to establish the students through their senior studies.
You're welcome - and thank you. Remember, V÷Ω=A. Volts and Ohms MAKE Amps... Have fun. Be safe. Be confident.
could you explain that more? we always learn that E=IxR and move on, which seems to suggest resistance and amps make volts
Tom Jennings check out the ohms law video by Jim pytel big bad tech.
Coulombs which is an amount of electrons is amps is what I was thought . Intensity
Im electrical first year student. yesterday one of my teacher ask what is voltage & current? nobody have no idea about it .but now i got it. thank you very much
so are there fewer amps in a circuit after it passes through a motor or resistor?
ua-cam.com/video/-w-VTw0tQlE/v-deo.html
YES
Motor or resistor would be a 'load'. The amperage depends on the load value in ohms. If there were no motor or resistor, it would be a short circuit, meaning infinite amperage, on paper.
This is the best ans easiest explanation that I've found! I have taken basic electrical and have struggled constantly because of all the math and letters. Thank you for making this!
This is Brilliant, thank you from Egypt :)
Thank you for the very easy to understand explanation! Ohms law is something that has shamefully eluded me in my career as an AV tech, now I have to take my OSHA30 and am to be tested on it! I feel much more confident I can do it now. :)
The explanation was very good except that I got confused at 5:42 in the video. After you close the switch, the high pressure electrons jump out of the box (where they are under higher pressure) on to the wire which has presumably atoms at lower pressure (nicely spaced out). But should they not end up at a positive terminal (where the pressure is much lesser than the negative terminal). Your video seems to connect box of high pressure electrons back to itself. Unless the flow is to a lower pressure box the currently should not flow continuously,
yeah.. that's what stumped me also. Normally, the electrons wouldn't flow at all in his setting because there is no difference in pressure. He should have divided the battery in 2, put a high density electron area and a low density area. The current flow should be from high to low density area until they balance eachother out and push against eachother equally,
You have both correctly identified the fundamentally wrong concept this video is based on. Electrons do not flow out both terminals of a battery. If they did, there would be no point of '+' and '-' terminals and you could jump-start a car connecting a battery any old which way (which is what Daniel's students would do which is why I won't let them near my car .... ever).
HES CRAZY
i agree. I think the video is splendid accept for that part. There it seems to be just wrong. The electrons travel through the wire, doing work etc. BECAUSE they want to go/are attracted to the positive charges in the other side of the battery. Of course this model also is a simplification, since there are chemical reactions going on at both sides of the battery, the sum which leads to a flow of electrons. But that is overcomeable. But the depiction at 5.42 is not. In the video there is no reason for the electrons to flow trough the circuitry, only to leave the battery.
@@por4258 Exactly.
I've learned more from you in 3 hrs than i've learned in all of my college and teaching career ...Thanks DS!!!!!
You are a gotdamn genius. Thank you for this.
Really a very helpful video. Thank you Mr Sullivan for making this video and sharing with everyone. After checking some reference books and asking some experts, nothing is clearer than what you shared. Thank you and the Lord blesses you!
You: "The force is pretty powerful"
Me with the attention span of a 2 year old : "Vader would agree"
THANK YOU SO MUCH. I've been trying to figure out the difference of Amps and Ohms for literally months. This has helped me so much, thank you!
No prob. I've been trying to figure out women for, like, 50 years. Electricity is waaaaay easier...
Daniel Sullivan Hahahahahaha. Well I could teach you a thing or two.
And you still don't get electricity, so no wonder you are single.
Thanks!! I have a science exam at 10:00 (it's 8:00 right now) and I was looking over the concepts I didnt get. Guess I check check this off the list!
+coolkidsahib Volts and Ohms **MAKE** Amps. Good luck.
Don't say good luck!!! Thats always bad luck for me! I started saying break a leg. :)
coolkidsahib Okay - then - shatter your pelvis... How's that?
Lool Thanks!! Thanks to you, I think I may have done good on the exam. Most of the electricity section was based on Volts Ohms and Amps, and I wasn't in class for those (I was doing our Christmas Show)
coolkidsahib I'm sure the atmosphere was electric. Hopefully the cast was a great group of high voltage people. You need to stay current in class. Don't put up too much resistance to asking questions... (See what I did there?)
Teaching has to be one of the most noble professions out there. A teacher of anything should be given as much respect as we give to our parents.
So voltage is like potential energy and amperage is like kinetic energy... kinda?
In a sense - yes. Not bad.
mickles1975 Voltage is the potential energy per coulomb of charge. The current is the rate of flow - as coulombs per second.
I'm glad you think that my videos are frequented by individuals with adequate education and background to understand your descriptions and explanations, but it's important to remember that I teach mechanics ------ the guys who sat in the back of class and were culturally ostracized. If we were as stupid as our teachers and counselors thought, nothing would run.
I've said it a million times - crawl, walk, run... If you (and many others) are as intelligent as your posts hope to prove, teach... But - crawl, walk, run. BTW - can you guys weld, wire a building, build a house, pour concrete, do masonry, operate a lathe or mill? Just curious. Occupation doesn't dictate intellect. The man makes the job, not vice versa.
can you guys...
weld, -yes
wire a building, -nope
build a house, -nope
pour concrete, -yes
do masonry, -nope
operate a lathe or -yes
mill? -yes
mickeybill Actually the correct answer for a tech is yes - for an engineer? No...
Great video! I love the "voltage pushes current thru resistors" great explaining. Thank you.
Well explained, thank you
No problem... Thank you.
Tom V. There you go being an arrogant ass again. Why do you have to be so bitter. If you don't like his teaching method shut the heck up and go away. No one is asking to watch. Jerk!! Ron H
I don't have a problem with the teaching "method"
I have a problem with the material taught.
Tom V What is wrong in the video ?
> Tom V What is wrong in the video ?
I believe I have made that abundantly clear. Pretty much everything in the original video is either incorrect or misleading to a terrible degree.
1) electrons are not scrunched up in a little box trying to get out.
2) Batteries have terminals. Positive and negative terminals. That is kinda important especially if you are hired to jump-start a car.
3) Pretty much everything else in the original video is wrong.
You can use the water analogy as a better guide to basic DC electricity. Go google.
Any other questions?
Thank you!! I will be sharing this with my grade 9 students. Not only will it help them but I too and more confident in understanding this concept!
Thanks!
+Fiona McCallum No problem - happy to help.
Oh, shit.
I still don't get it.
That's because the explanation is completely wrong. You would do better checking out a course on Coursera or Khan Academy, or just plain googling around plenty. The concepts here couldn't be more flawed than they are.
Tom Vilot if this is wrong, and you are so adamant to point this out, why not make a video correcting the errors. Nothing worse in this world than a man that won't contribute to his fellow man, yet sits at the table to eat their food.
BUT OHMS LAW IS MEASURED WITH MATH TO GET THE ACCURATE LEVELS.... SO WHY IS IT NOT AN EQUATION. ? IF NOT YOU WOULD NOT KNOW THE NUMBERS YOU NEED TO KNOW THE CIRCUIT. DUH?
I just completed a course from tpc and after the course, you will get a better idea of electricity. I have worked with electrical components and motors for years. After the course, I have a better idea of how it works plus the safety involved. You can't see it and you can't feel it until it's too late. Be cafeful, follow basic rules and you should be okay.
@@tomv3999 Is it completely wrong to exaggerate, or partial?
My hat's off to ya! Perfect way to explain a topic like this to general public!
you didnt explain amps.
Yeah. He didn't explain voltage, either. Nor ohms. Because he doesn't know what the *#$^! he is talking about.
@@tomv3999 Absolutely right.
Dan well done. It was clear and understandable. Many years ago I took "Electricity" in high school and never understood the physics part of what you were able to explain in eight minutes.
52 people have too much negative charge
DOH!!! I’m 58 and I always thought that high tension wires on the poles meant the way they were strung, like in engineering tension and compression of the actual wires, not the stuff inside them. Wow do I feel stupid at the moment but then nobody ever explained what they were, just pointed and said, they are high tension wires, don’t touch or they’ll kill you. Hmmmph. I’m only half way through but had to stop and interject. I’ve known the formulae etc and have used over the years but I’ve never truly understood how electricity worked but now I think I starting to understand and hopefully you will continue to teach me and I will continue to learn from you. I cannot tell you how grateful I am to stumble upon your video on this, the last day before 2020 comes, what a great new way to start a new decade, thank you
i dont think anyone knows how magnets work.....just saying.....i mean noone knows how they ACTUALLY work
Yep - you're right...
Hmmmm
> i dont think anyone knows how magnets work.....just saying.....i mean noone knows how they ACTUALLY work
It's not that complicated and has been understood for quite some time. Electrons. Atoms. Materials. It's not that hard to follow (unless Daniel is teaching the course, in which case you are completely f&cked).

@@tomv3999 My god you are so incredibly annoying. It's like someone attached a megaphone to a mosquito and let it fly around the comments section for three hours.
I teach this in welding, and it really helps the students understand where the heat is coming from; arc created through resistance, and only works when you're a certain distance away at all times. Air is a great insulator.
lol seeing as ur smarter than my science teacher, i should just stop going to school (.....actually.....everyone is smarter than my science teacher, hes an idiot...proof, you know those vandograph static hair-go-up thingys? he says those creates 200 000 volts. Thats frikin enoght to power my entire school!!!!!!!!))
I wouldn't have questioned your teacher. Van de graff generators can easily get that much voltage- he's right
I think if you want a science teacher that will guarantee you fail to graduate high school, you need look no farther than Daniel's video.
this stuff is so hard to learn but you explained so well that it'll now stick in my head forever. thanks!!
From one teacher to another you might want to let up on the metaphors. "The electrons are upset and have stress" Relating electrons to a human emotion just confuses people and has nothing to do with what they do. Also you are writing TOO much. is slows the learning process and does NOT help with memorization. Pictures are good but don't spend a lot of time making them really cool, again it slows things down. Watch a couple of Veritasium when he writes and draws Magnetism is a good one. Good luck.
Fist up, Fight for Truth.
Thanks, but you watched one of my first videos. I've gotten better over two years, and with respect, from one teacher to another, it's worked for 28 years, so I'll keep at it. However, I do appreciate criticism. Depending upon who and what you teach, you may or may not appreciate that teachers are by far the most critical, and seldom without some ego involved. Not knowing you I can't say, but people either love me or hate me. Most respect me. Feel free to comment, but it would help me more if you watched number 80 too.
Going to have to disagree with you. I thought that the way he presented this was actually pretty refreshing and wish I had a teacher in university that explained ohms law to me like this. If the metaphors in this video actually confused anybody then understanding ohms law and other fundamentals of electricity probably wasn't in the cards for them to begin with.
What a negative electron lol
He was trying to be helpful - but I'm a cartoonist.
From a student to two teachers. This is a good video and the explanation and art we spot on.. Thanks D, love your vids..
Wow! That was fantastically illustrated! By far the best explanation of the basics of the concept of electricity out there.
i paused only to say that you are a very good teacher !!!
it is not enough just to know to be a teacher
you also need to be able to transfer your knowledge . excellent from me.
Thanks a lot.
This is the best explanation of the voltage I've ever seen.
Highly appreciated 👍
THIS TEACHER IS SO GOOD... THE GUY KNOWS HIS STORY... ITS BROKEN DOWN TO ITS SIMPLEST FORM
Thank you for putting this together and the drawn illustration really helped explain in a simplistic manner.
Thank you very much. You are the BEST in the business!What great teaching! I AM VERY GRATEFUL...FOR ANYONE WHO WANTS TO UNDERSTAND THESE CONCEPTS , HE IS YOUR BEST BET!!!
This was invaluable for me as someone new to electronics/circuitry. Much appreciated.
Dear Daniel, thank you very much for this video. It really helped me understand what voltage and Ohm's law are!
Excellent. One step closer to understanding the mysteries of electricity and circuits. Thank you.
