I am an engineer, but I haven’t seen all your videos. I still recommend them to students. For purposes of the home handyman, I hope you cover an explanation of why the AC in basic home wiring has a hot wire and a neutral wire if alternating current means alternating flow of current. My rough and dirty explanation to friends, just so they learn to be safe, is that one side is active and the other, a current carrying ground, is passive, but never take wire color for granted. Always identify the hot wire and account for why it is the hot wire in whatever box you find it.
if the electric current is the flow of electrons, then the electric current should also flow from the negative terminal to the positive terminal, but why the electric current flows from the positive terminal to the negative terminal

Key point I think was overlooked: the more electrons in the outermost shell, the stronger the nucleus holds onto them. This is why materials with just one valence electron (living in the outermost shell) make the best conductors of electricity-they are the loosest held by the atom. Valence electrons even make the atom smaller.... an atom with two valence electrons will be just slightly smaller in diameter than the atom with one less proton/electron: the nucleus holds the electrons tighter and closer, which makes the atom's diameter slightly smaller. The metals copper, silver, and gold are excellent conductors because they have one valence electron and the size of the atoms is a "sweet spot" for how loosely that valence electron is held.

That’s actually very common in trades, most electricians focus on the practical knowledge that’s gets the job done like electrical codes and techniques. It’s not necessary to fully understand the science behind it but it does set you apart from the rest if you decided to inform yourself on electrical theory. Most Journeyman and master electricians have at least a basic knowledge of this stuff.

You know your "dyslexia" is actually natural & intuitive, because Ben Franklin got it wrong.

It’s been a few years after college for me, so I’m starting from the beginning to recap on things I’ve forgotten. I appreciate the time and effort you’ve taken to make these comprehensive videos to be easily understood
I used to tell my late Papa that I will be an engineer one day others say you are a girl can you not follow another career you know what engineering is a talent i am able to fix phones, speakers and touch light iam 19years old iam hoping soon to go to university never give up on your career you are strong the way you are .
The ease with which the narrator describes the subject shows that he is the master of what he is talking about. Many thanks for this instructive video.
I'm a car mechanic and I have become fascinated with electricity recently. I also am reading 20,000 Leagues Under the Sea in which you can see how electricity in the 19th century really mesmerised the scientific and public world. These videos are really helpful for a beginner to start understanding what electricity is!
Electrons actually move very slowly through a wire connected to some voltage source. What really happens is the electric field sloshes the electrons in the direction we call the direction of current flow and the electric field propagates very close to the speed of light. Slightly less since it's not a vacuum.
I'm in 7th grade and I'm trying to learn about electrical engineering so I can learn how to build my own machines. Building machines is a very special interest for me and I mainly wanna learn about these things to make my family proud. This video was very helpful 100/10!! :D
Great video, short & to the point as it should be! --------- 01:30 INSULATOR: atoms without free electrons in valence shell CONDUCTOR: atoms that can pass electrons - surround with insulator (e.g. copper wire inside rubber) 02:15 Atoms are passed randomly in any direction Connect conductive material to CLOSED circuit with power source -> 03:09 VOLTAGE (pushing force, analogy: pressure in water pipe) forces electrons to move in same direction, trying to get to the other terminal 03:23 VOLT= work (Joules, heat/light) per group of flowing electrons (Coulomb) 03:59 AMP = unit of current (analogy: flow of water in pipe), 1 Amp = 1 Coulomb/second 04:37 RESISTANCE (unit = Ohms) = restriction on flow of electrons -- factors: length (longer = more resistance), thickness (thicker = less resistance), material (copper has lower electron collision rate than iron -> copper offers less resistance), temperature (hotter = less resistance) In circuits without inductances or capacitance Ohm's law: Voltage (V, in Volts) = Current (I, in Amps) * Resistance (R, in Ohms) -> Current = Voltage / Resistance & Resistance = Voltage / Current Power (P, in Watts) = Voltage * Current 04:59 RESISTORS restrict flow of electrons, e.g. protect other components or create light/heat (05:16 high enough collission rate of electrons due to resistance => incandescence) 05:40 INDUCTOR - coiling a wire intensifies its natural magnetic field as current passes through it -> electrons in wire become affected. More turns in coil / iron core / more current ---> stronger magnetic field ---> electromagnets + induction motors 06:27 AC GENERATORS; passing magnetic field THROUGH coil -> induced electromotive force -> induce voltage, cause current to flow if in circuit 06:52 TRANSFORMERS: induce voltage from primary coil (in circuit with AC generator) over into a secondary (proximate but not touching) coil (in CLOSED circuit). => allows to increase/decrease voltage between primary and secondary coil by changing amount of coils on either side. 07:38 CAPACITOR ("condensator" in multiple languages): separates positive and negative charges across 2 plates if connected to power supply -> build-up of electrons in electric field ... interrupted power supply -> charges released (power source for few seconds) + pair back up again 08:17 ALTERNATING CURRENT (AC): current flow backwards & forwards as terminals are reversed, most common (wall sockets,...) DIRECT CURRENT (DC): current flows only in 1 direction (batteries, handheld devices, solar panels)
Wow thx for the notes can you please explain at the generator part that 1st current through a coil was causing mag field then he said mag field generates emf and then causes current in the same coil so how that works I mean there was already current flowing through source before so now we don't need source? And will this mag field provide current now to the circuit?
UA-cam suggested me this gem after 3 years!!!!🙄🙄 . . There must be any open circuit or highly resistive path... 😜😜😜😜 Hats off guruji... 🙏🏻🙏🏻 Crystal clear explanation 👍🏻
One of the best videos I've seen on electricity. I learned more from this 10 minute video than I did going to 13 years of school or in my 26 years of my life.
Paul thank you for these great teaching/learning videos. The time, planning and production to create all these wonderful videos is tremendous and greatly appreciated. Thank you again. I learn and gain a much deeper understanding of the study of electricity with each video.
I have watched multiple video of your today, all are of electromagnetic. These videos not just clear the basic concept but the live diagrams make it really easy to visualise. Also you talk about their usage in daily life makes it interesting. Thank you
Best background lesson I've ever had on my desk! Comprehensible, easy to listen to, very well illustrated. Thank you so much. I can't count the times I've backed up to confirm that I actually "get it" for the first time in ever!
When I was a kid my dad used to work at a hospital and he was allowed to let me visit during lunch. One day we were sitting at a picnic table set up just next to a transformer. Being the curious kid I was I asked my dad what “the big green humming box” was. He told me it’s a transformer. I simply replied “oh.” When I had to go home so he could go back to work I went up to the transformer and said “your secret is safe with me”
I just got acepted to take the electrical course. I’ll finish this playlist at least 5 times before the classes start in April just so I have a little above the basics
New subscriber here. Just learning how electricity works. Have to watch it a couple of times. Its like learning a new language. Hope i can last in my quest of upgrading my knowledge on this subject Thank you sir for the lesson.
Thank you very much for this video it's knowledge video for students beacuse I am studying in class 7 in our science book there have this ch electric current and its effects...... Thank you 😊 💓
I Can't believe I paid thousands of dollars for schools just for a piece of knowledge that I can get for free in 10 minutes from UA-cam, Mr engineering mindset you are a lifesaver
Joseph Colletti I figured this comment would be here. 1A does not equal 1C, but rather 1C per second. 1C is a measure of number of electrons, not based in time.
Thank you, I had to rewatch a couple of times as I'm relearning the basics. Eventually figured out that what he said was right, but the slide was wrong.
Once I Done Watching All Electrical Engineering Basics Videos, I'm Going To Treat Myself To One Of Your Hoodies. These Videos Really Got Me Learning Like I'm In University. Great Job!
Ever since I started watching these videos, they have been a great help to me, and learning a lot better than the ones I watched in College. Thanks for the videos, I'll be viewing more of them!
Something important to know about transformers: transmormers cannot function with Direct Current (DC), you can use a transformer only with Alternating Current (AC)!
Currently doing up a boat! I've got electricians doing the work but when they ask me questions I'm baffled. Came by, watched, got schooled now I'm going to go answer their questions. Also, my Dad is an engineer and as a kiddo he could never explain anything to me as simply as you just did. Thank you so much, Liz
Dude I got one :) 3 buddies decided to get drunk one weekend. Mr. Proton, Mr. Neutron and Mr. Electron. Went in got drunk and then asked the bartender for the tab. Barkeep goes "For Neutron, no charge but there will be a charge for Mr. Electron here" Mr. Proton got mad and asked "What?! no charge for my buddy Mr. Neutron?! Are you positive?!" Bartender replied "No, but you are"
Great video. Unfortunately, as in the video explaining current, the presenter mixes up charge (measured in Coulomb) and current (measured in Ampere), stating that Ampere=Coulomb and that coulomb is a certain number of electrons per second, which is not the case. Since this is very basic stuff, it ought to be corrected.
Had to believe guys like this are out there. What's my business with classrooms when i gat this in my PC? You're the man I swear. These are saving grace where teachers are getting us confused
Awesome! The atomic level really helps my understanding. Nobody has ever tried to explain electricity to me at the atomic level. I love how resistance is described as the "number of electron collisions with other atoms". That is much easier to understand than the text book definition "measure of its opposition to the flow of electric current". Thanks!
Amazing. Brilliantly explained. Now why couldn't my teachers explain the fundamentals of physics with such clarity and concision when I was at school ?
I had already accepted that I'd never understand how electricity works but aften watching a ton of videos similar to this, this one actually made a little sense
This is exactly the picture i had in my head!!! Thank you for confirming my speculations! I've been looking for this type of videos to connect the gaps i have in my head!!!! Thank you!
Up until this point (and probably due to public school) I’ve just assumed the position that electricity is just magic I will never understand. This video was super informative and explained all my questions. Thank you!
*summary:* - the electrons in the valence shell (outter shell) of some atoms can flow from one atom to a neighboring one - if you create an *electric potential* (aka *voltage*) difference across a *conducting* wire, the electrons will flow in one direction through that wire - if you cut out a small piece of the conducting wire, and replace it with a *resisting* wire, the resisting wire will get hot as electrons flow through it - you can use this concept to create things live electric stoves, heaters, etc - there are certain resisting material, that when heated up, will produce a lot of bright light, you can use this to create electric light bulbs *units:* - *voltage* is a measure of electric potential difference between 2 points in a conducting wire - the unit of voltage is *Volt* - a Volt is the number of joules of energy given of as 1 coulomb of electrons flows from one point to the other - a *coulomb* is just a really large number - *current* is a measure of how many electrons are flowing through the wire per second - the unit for current is *Amps* - 1 Amp is 1 coulomb of electrons lowing past a certain point in your wire per second *briefly covered stuff:* - an *inducer* is a coil of wire, that generates a magnetic field in response to current going through the wire - the magnetic field creates a voltage in the opposite direction as the current - this is how AC (alternating current) is produce - *AC* is when you move electrons in one direction in the wire, then in the opposite direction, then in the original direction, then in the opposite, and repeat - *DC* (direct current) is when electrons move in the same direction the whole time - a *capacitor* builds up charges as current flows through it (when current stops flowing, the charge dissipates) Thanks for this video! Extremely well made!
Sorry for the basic question: when you say "magnetic field creates a voltage in the opposite direction as the current", can you explain what does mean *direction* for voltage? I understand that a current has a direction (direction of flow of electrons) but what does direction mean for voltage?
Truth behold i have never gotten a true grasp of how electricity works until i just watched your video and right at 2:30 i had a turning point.That made everything i had learned before finally made sense you have changed my life for the better thank you.
Electricity/Electric field is a combination of dielectric field (electrons) + magnetic field. Both fields cross each other at 90 degree angle to produce AC or DC electric field you are familiar with. See Steinmetz diagram on page 10 and 11 in his book "Elementary lectures on electric discharges, waves and impulses, and other transients". You can also see dielectric field as voltage and magnetic field as current. Both fields together create power measured in watts.
Well technically the electrons do not follow an orbit around an atom the way a satellite orbits a planet, there's the whole particle-wave duality and whatnot. But I suppose that doesn't really matter as long as the valence electron(s) are able to switch atoms easily. I'm sure you knew that and just made the video simpler, but it felt somewhat inaccurate to me. That being said, amazing video and I learned some useful stuff from it. Got yourself a new subscriber.

I used to tell my late Papa that I will be an engineer one day others say you are a girl can you not follow another career you know what engineering is a talent i am able to fix phones, speakers and touch light iam 19years old iam hoping soon to go to university never give up on your career you are strong the way you are .
Fair play! I hope everything’s going well.
If you believe you can achieve it, you can. Keep it up.
Thank you so very much
Good luck!

The ease with which the narrator describes the subject shows that he is the master of what he is talking about. Many thanks for this instructive video.
I'm a car mechanic and I have become fascinated with electricity recently. I also am reading 20,000 Leagues Under the Sea in which you can see how electricity in the 19th century really mesmerised the scientific and public world. These videos are really helpful for a beginner to start understanding what electricity is!
I hope we got another tesla who can upgrade the electricity knowledge to the high
Electrons actually move very slowly through a wire connected to some voltage source. What really happens is the electric field sloshes the electrons in the direction we call the direction of current flow and the electric field propagates very close to the speed of light. Slightly less since it's not a vacuum.
correct, the picture is wrong
Refreshing my mind from high school (37 years ago) when I took Radio & TV repairs classes.
My high school syllabus in 10 mins. Only if I'd understood these things so clearly back then, I'd have been a better engineer... 😰
There's still time
12th NCERT?
Right!😁
👍
@@EngineeringMindset there always is. age is just a number.
I'm in 7th grade and I'm trying to learn about electrical engineering so I can learn how to build my own machines. Building machines is a very special interest for me and I mainly wanna learn about these things to make my family proud. This video was very helpful 100/10!! :D
Great video, short & to the point as it should be!
---------
01:30 INSULATOR: atoms without free electrons in valence shell
CONDUCTOR: atoms that can pass electrons - surround with insulator (e.g. copper wire inside rubber)
02:15 Atoms are passed randomly in any direction
Connect conductive material to CLOSED circuit with power source -> 03:09 VOLTAGE (pushing force, analogy: pressure in water pipe) forces electrons to move in same direction, trying to get to the other terminal
03:23 VOLT= work (Joules, heat/light) per group of flowing electrons (Coulomb)
03:59 AMP = unit of current (analogy: flow of water in pipe), 1 Amp = 1 Coulomb/second
04:37 RESISTANCE (unit = Ohms) = restriction on flow of electrons -- factors: length (longer = more resistance), thickness (thicker = less resistance), material (copper has lower electron collision rate than iron -> copper offers less resistance), temperature (hotter = less resistance)
In circuits without inductances or capacitance Ohm's law: Voltage (V, in Volts) = Current (I, in Amps) * Resistance (R, in Ohms) -> Current = Voltage / Resistance & Resistance = Voltage / Current
Power (P, in Watts) = Voltage * Current
04:59 RESISTORS restrict flow of electrons, e.g. protect other components or create light/heat (05:16 high enough collission rate of electrons due to resistance => incandescence)
05:40 INDUCTOR - coiling a wire intensifies its natural magnetic field as current passes through it -> electrons in wire become affected.
More turns in coil / iron core / more current ---> stronger magnetic field ---> electromagnets + induction motors
06:27 AC GENERATORS; passing magnetic field THROUGH coil -> induced electromotive force -> induce voltage, cause current to flow if in circuit
06:52 TRANSFORMERS: induce voltage from primary coil (in circuit with AC generator) over into a secondary (proximate but not touching) coil (in CLOSED circuit). => allows to increase/decrease voltage between primary and secondary coil by changing amount of coils on either side.
07:38 CAPACITOR ("condensator" in multiple languages): separates positive and negative charges across 2 plates if connected to power supply -> build-up of electrons in electric field ... interrupted power supply -> charges released (power source for few seconds) + pair back up again
08:17 ALTERNATING CURRENT (AC): current flow backwards & forwards as terminals are reversed, most common (wall sockets,...)
DIRECT CURRENT (DC): current flows only in 1 direction (batteries, handheld devices, solar panels)
Wow thx for the notes can you please explain at the generator part that 1st current through a coil was causing mag field then he said mag field generates emf and then causes current in the same coil so how that works I mean there was already current flowing through source before so now we don't need source? And will this mag field provide current now to the circuit?

There must be any open circuit or highly resistive path... 😜😜😜😜
Hats off guruji... 🙏🏻🙏🏻
Crystal clear explanation 👍🏻
Easy to learn things when the teacher has a calming accent
Thank god he’s not cockney haha
Can fans donate to the channel to you never stop making these videos
One of the best videos I've seen on electricity. I learned more from this 10 minute video than I did going to 13 years of school or in my 26 years of my life.
Glad you liked the video, but what the hell were you doing in school to learn less than 10 minutes worth of a good video in 13 years?
@@rubenornesa8405 playing video games and watching anime
Best electrical videos on the internet - exceptionally explained. Thank you for all of your efforts!
Paul thank you for these great teaching/learning videos. The time, planning and production to create all these wonderful videos is tremendous and greatly appreciated. Thank you again. I learn and gain a much deeper understanding of the study of electricity with each video.
UA-cam channel is one of the best tutorial channel for electrician
Bro explained my entire physics syllabus in 10 minutes better than my teacher could do in a year 💀👏🏻
😂😂
Wish you were my school teacher. would have definitely done something huge in physics !
I have watched multiple video of your today, all are of electromagnetic. These videos not just clear the basic concept but the live diagrams make it really easy to visualise. Also you talk about their usage in daily life makes it interesting. Thank you
just wow! i'm blown away by how good these videos are, loved the capacitor and battery analogy!
Best background lesson I've ever had on my desk! Comprehensible, easy to listen to, very well illustrated. Thank you so much. I can't count the times I've backed up to confirm that I actually "get it" for the first time in ever!
Thank you! I dropped out of studying the sciences because I couldn't visualize it. This is so helpful.
Very good lesson, so interesting tips, thank you for the sharing.
When I was a kid my dad used to work at a hospital and he was allowed to let me visit during lunch. One day we were sitting at a picnic table set up just next to a transformer. Being the curious kid I was I asked my dad what “the big green humming box” was. He told me it’s a transformer. I simply replied “oh.” When I had to go home so he could go back to work I went up to the transformer and said “your secret is safe with me”
LOL! I wondered where this comment was going! Good one!
I just got acepted to take the electrical course. I’ll finish this playlist at least 5 times before the classes start in April just so I have a little above the basics
Great idea mate, you will succeed. 👍
Yeah, i don't get it.
Its ok me neither and I am EE
try breaking things down into parts, no shame in slowing it down.
😂😂😂😂
U didn't get that I also don't worry let's go to the other chanel
New subscriber here.
Just learning how electricity works. Have to watch it a couple of times. Its like learning a new language. Hope i can last in my quest of upgrading my knowledge on this subject
Thank you sir for the lesson.
Your videos are just amazing! Great explanations and animations. Thank you very much for your work!❤
Thank you. This is an excellent channel, one of the few that can explain electricity in easy-to-understand terms. Many can’t.
Great video. It explained what I have learnt in 1 year physics class in just 10 minutes.
Love it. It's boring for us that have known this material, but for a curious kid it's exactly what the internet should be used for.
Thank you very much for this video it's knowledge video for students beacuse I am studying in class 7 in our science book there have this ch electric current and its effects...... Thank you 😊 💓
I Can't believe I paid thousands of dollars for schools just for a piece of knowledge that I can get for free in 10 minutes from UA-cam, Mr engineering mindset you are a lifesaver
This is one of the best videos I've ever seen on electrical theory
Thank you so much for this video.It's really helpful and excellent.
Wow, an engineering video with a narrator who can speak through a single sentence. Thanks for the rare video with tolerable narration
Excellent job! I watched several of your videos now and you have done a top-notch job explaining electricity and electrical engineering!
Excellent video. Seriously.
lol
Great videos
But you need to correct the ‘current slide’ ~4:30
1A=1C/s=6.242E18 electrons/s
Joseph Colletti I figured this comment would be here. 1A does not equal 1C, but rather 1C per second. 1C is a measure of number of electrons, not based in time.
Thank you, I had to rewatch a couple of times as I'm relearning the basics. Eventually figured out that what he said was right, but the slide was wrong.
At 4:30 is the number just wrong on the slide?
Once I Done Watching All Electrical Engineering Basics Videos, I'm Going To Treat Myself To One Of Your Hoodies. These Videos Really Got Me Learning Like I'm In University. Great Job!
Thank you for helping me understand what my school barely put in the effort to explain.
This is so useful!!
When discussing current you state Ampere = coulomb should be ampere =coulomb /second
Also, One Coulomb is just equal to the charge on 6.241 x 10^18 protons
Ever since I started watching these videos, they have been a great help to me, and learning a lot better than the ones I watched in College. Thanks for the videos, I'll be viewing more of them!
Something important to know about transformers: transmormers cannot function with Direct Current (DC), you can use a transformer only with Alternating Current (AC)!
Currently doing up a boat! I've got electricians doing the work but when they ask me questions I'm baffled. Came by, watched, got schooled now I'm going to go answer their questions. Also, my Dad is an engineer and as a kiddo he could never explain anything to me as simply as you just did. Thank you so much, Liz
Same here learning all of this so I can fix up my boat!
cool video, it helps not only kids, it refreshes engineering students too. thx a million.
Dude I got one :) 3 buddies decided to get drunk one weekend. Mr. Proton, Mr. Neutron and Mr. Electron. Went in got drunk and then asked the bartender for the tab. Barkeep goes "For Neutron, no charge but there will be a charge for Mr. Electron here" Mr. Proton got mad and asked "What?! no charge for my buddy Mr. Neutron?! Are you positive?!" Bartender replied "No, but you are"
Mac Cullete love it.
Nice ONEONE
Hahaha
Mac Cullete boo hiss
brilliant.. come over for some biscuit and tea
I spent a little time writing this comment. But no words could express my full gratitude. Thank you so much.
my head hurts, no way im cramming this all up in a day
Amazing and incredible graphics and animations with a brilliant explanation. That's extraordinary!
At 5:00 , I love how he used a sine wave to represent smoke as a result of the LED bulb breaking.
Hy , The Engineering Mindset I am from India and I watch most of the video. And then i think you are great teacher.
Thank you, do you know we also have a Hindi channel? ua-cam.com/channels/g4k338hz9U8jnD5SXPO5jQ.html
I wish I had a teacher which explains these basics exactly like you , Thanks and appreciated !
This video was uploaded 3 years ago but its still the best explanation i have seen so far. Thanks man. Keep it up.
Great video. Unfortunately, as in the video explaining current, the presenter mixes up charge (measured in Coulomb) and current (measured in Ampere), stating that Ampere=Coulomb and that coulomb is a certain number of electrons per second, which is not the case. Since this is very basic stuff, it ought to be corrected.
I'm leaving this for tomorrow 2 MINUTES IN because I've noted down so much info already!! This is wild!!
This 10 minute video made me understand things that i haven't understood from years of study in School
In a 10 minute video you elegantly sum up 6 weeks of teaching in a first year engineering paper
Thank you for making such useful videos. Because of this video I understood so much on electricity and it's working. THANK YOU ONCE again....
Had to believe guys like this are out there. What's my business with classrooms when i gat this in my PC? You're the man I swear. These are saving grace where teachers are getting us confused
I am a 4th year computer engineer and today I finally understood what I was learning in class.
Well now I know my future is gonna be bright after watching this
Awesome! The atomic level really helps my understanding. Nobody has ever tried to explain electricity to me at the atomic level. I love how resistance is described as the "number of electron collisions with other atoms". That is much easier to understand than the text book definition "measure of its opposition to the flow of electric current". Thanks!
I’m a 1st year hvac apprentice and I just want to thank you for what you do bro. Your videos are a lifesaver 👏🏾
way clearer explanation than any engineering book I've ever encountered
So many concepts covered in a single video !!! GOod job man... Looking forward to complete the series ..
Your engineering videos are very useful and your animation style is excellent and best technique for understanding
Amazing. Brilliantly explained. Now why couldn't my teachers explain the fundamentals of physics with such clarity and concision when I was at school ?
I had already accepted that I'd never understand how electricity works but aften watching a ton of videos similar to this, this one actually made a little sense
This is exactly the picture i had in my head!!! Thank you for confirming my speculations! I've been looking for this type of videos to connect the gaps i have in my head!!!! Thank you!
Up until this point (and probably due to public school) I’ve just assumed the position that electricity is just magic I will never understand. This video was super informative and explained all my questions. Thank you!
AC/DC explanation so simple. Thank you for this. I am trying to learn about electricity. Your videos are very helpful.
Watching this video and seeing all the comments.. I'm simply loving it...
*summary:*
- the electrons in the valence shell (outter shell) of some atoms can flow from one atom to a neighboring one
- if you create an *electric potential* (aka *voltage*) difference across a *conducting* wire, the electrons will flow in one direction through that wire
- if you cut out a small piece of the conducting wire, and replace it with a *resisting* wire, the resisting wire will get hot as electrons flow through it
- you can use this concept to create things live electric stoves, heaters, etc
- there are certain resisting material, that when heated up, will produce a lot of bright light, you can use this to create electric light bulbs
*units:*
- *voltage* is a measure of electric potential difference between 2 points in a conducting wire
- the unit of voltage is *Volt*
- a Volt is the number of joules of energy given of as 1 coulomb of electrons flows from one point to the other
- a *coulomb* is just a really large number
- *current* is a measure of how many electrons are flowing through the wire per second
- the unit for current is *Amps*
- 1 Amp is 1 coulomb of electrons lowing past a certain point in your wire per second
*briefly covered stuff:*
- an *inducer* is a coil of wire, that generates a magnetic field in response to current going through the wire
- the magnetic field creates a voltage in the opposite direction as the current
- this is how AC (alternating current) is produce
- *AC* is when you move electrons in one direction in the wire, then in the opposite direction, then in the original direction, then in the opposite, and repeat
- *DC* (direct current) is when electrons move in the same direction the whole time
- a *capacitor* builds up charges as current flows through it (when current stops flowing, the charge dissipates)
Thanks for this video! Extremely well made!
Abdullah Aghazadah Man U deserved the MVP on comment section
@@tashitsenkyap21 Haha :P, thanks man
Fest hos abdullah, abdullah åh ah
Sorry for the basic question: when you say "magnetic field creates a voltage in the opposite direction as the current", can you explain what does mean *direction* for voltage? I understand that a current has a direction (direction of flow of electrons) but what does direction mean for voltage?
gosh thank u man i really needed this for my task lol
Thank you so much Sir for this amazing knowledge. This is really going to help me in my apprentice electrician journey. Thank you so very much.
Truth behold i have never gotten a true grasp of how electricity works until i just watched your video and right at 2:30 i had a turning point.That made everything i had learned before finally made sense you have changed my life for the better thank you.
Absolutely easy to understand...
Love and thanks from BANGLADESH.....
4:17 1 ampere = 1 C / second. Coulumb is the unit of electric charge, so it represents quantity not rate!
Electricity/Electric field is a combination of dielectric field (electrons) + magnetic field. Both fields cross each other at 90 degree angle to produce AC or DC electric field you are familiar with. See Steinmetz diagram on page 10 and 11 in his book "Elementary lectures on electric discharges, waves and impulses, and other transients". You can also see dielectric field as voltage and magnetic field as current. Both fields together create power measured in watts.
Well technically the electrons do not follow an orbit around an atom the way a satellite orbits a planet, there's the whole particle-wave duality and whatnot. But I suppose that doesn't really matter as long as the valence electron(s) are able to switch atoms easily. I'm sure you knew that and just made the video simpler, but it felt somewhat inaccurate to me.
That being said, amazing video and I learned some useful stuff from it. Got yourself a new subscriber.
This made understand so much I never got in school!
