- 073 - Resistors and Capacitors
In this video Paul Andersen explains how resistors and capacitors affect circuits. The resistance of a resistor is affected by the resistivity of the material and the geometry of the resistor. The current through a resistor can be determined by Ohm’s Law. The capacitance of a capacitor is affected by the dielectric constant and the geometry of the capacitor. The charge of a capacitor is the product of the potential difference and the capacitance.

Ahhh.. Mr. Anderson, what a pleasant surprise.. we meet again.
Only single video on UA-cam with these types simulations and expert explanation
I love how your videos are short yet so informative. You introduce the topic, give us examples and equations to use. Short, simple, and effective!
I thought it would take me all afternoon to understand the concepts from my lectures, but all it took was this video. Thank you! :)
Greatest video I've seen about this subject. So so much information in 10 minutes. Very great video, thank you!
Wow this was ridiculously good. Thanks for explaining what they do and how they work in such a simple and clear manner!
Excellent presentation and visuals!!! Thanks
I learned more from this 10 minute video than my 3 hour mech class..
haha
@@prashanthprakasam8246 ?
no , it's 9.15 minutes lol
Excellent explanation... specially the Water pump analogy... easy to understand... I wish these videos would have been 25 years back when I first read about Capacitors in class 12. It will be of great help to students.
Back in the early 1960's when I was a young boy, my friends and I used to walk out to the City Dump grounds, they were open then, no supervisor to be found and no gates restricted access, so we could search the huge pit where the garbage truck dumped daily after it's rounds. I used to pick up all the old radio's and other electronic devices from back then and take them home to play with. One of my favorite things was to find the old wax covered capacitors and tear them apart, ribbons of foil and waxed paper were all over my floor after I had torn down an old set, the variable resistors went into my parts drawer, and speakers were mounted inside my dressers, and even the home made hi-fi that I built out of an old receiver, a .45RPM record record changer deck, and some plywood over the face of an old book case with some cloth I found in the Attic. Eventually that went into my teenage sugershack an old granary that was on the home place, no longer used for such purposes. I converted it into two rooms, a bedroom and living room with an abandoned couch, old recovered and repaired TV set, and my Hifi. Man the times we had but that would be another story
@Steve Steve Its sad I'm 12 year old now I actually wish I could do stuff like this now but with today's rules its really hard for kids to explore and be creative without being forced to
@@octaviusgalacticus2253 hey dont say that, there aint nothing that can stop curiosity!
I m 15 and boy have i been doin all these weird stuff with my friends for a while now!
We ve been ripping all our toys ever since we were little and we ve tried to make our own stuff with it (we failed at all our attempts tho, obviously)
I live by a coast and flooding is common here! I remember trying to make a boat with my friends a few years ago with motors and push swtches that we had ripped from my friends rc cars and...it worked! ( After a gazillion tries tho)
So yea...!
Never give up i guess!
Wow tell us more!
Well , learn must more than i did in college, thanks. Clear and direct explanations with simple language. Thanks
My god! The visualization is mind-blowing. Hats off to you sir
Dude, thank you so..much you rock!!! Love your tutorials! Cheers
great explanation and animation. helped me to better understand the concepts
What a useful lesson,thank you so much professor
Excellent explanation ,it's really helpful
Great explanation as usual, thank you.
Thank You so much - Very well explained and Excellent examples - even my 5 years olf understand it - Well Done - More please
nice, ocean of knowledge in 9.15 minutes
explanation so direct that my brain hurts :D thanks dude, subbed!
I am your greatest fan of you.thank you for all your videis.
so helpful. so easily explained. Thanks
Wow man! Very good video! I like what you're doing! Teaching people how to work the magic of circuitry and hardware haha
Great explanation, thanks
Thanks a lot. extremely helpful video :)
you are a great teacher.
thank you so much for this video!
Excellent information.
Very Helpful!
ur awesome u helped me alot in my science watching ur videos keep them going i watched ur dna replication vid and ya good vids u have a new sub
Best tutorial ever!!!!! Thank you!
I agree
Thanks, very clear explanation
very educative. Thank you regards
Very helpful for a guy who has never taken any class, ever, in electronics. Thanks!
Very well done.
I owe you like 1 semester of tuition lol thank you so much
I've always wanted electronics to be expressed in depth, in the simple manner you achieve.......:-) cheersrob
Amazing content
I knew nothing before this video, thanx professor
Man..... that's awesome....
Good explanation thanks a lot
awesome, professional
Capacitor, current leads the voltage? Wonderful visuals. Very informative.
Thank you.
What really happens, is that current is delayed by 3/4 of a cycle in a capacitor. If you look at the transient operation of an initially de-energized capacitor, when first subjected to AC, you will find that current doesn't really lead the voltage. It is just that it appears to lead the voltage in the steady state, which is usually what matters most of the time.
In the steady-state, delaying current by 3/4 of a cycle, is mathematically equivalent to current leading the voltage by 1/4 of a cycle. And when we only care about the steady state behavior, this is good enough for our purposes.
Many times better than crash course
Rick Grassi for real. Crash course isn’t that good and I don’t like their attitudes lol
crash course is shit. they dont make it simple for us. its just the animation that people go for
Its more feels more like a revision channel than a learning channel.
(Not being rude tho some lectures have seriously saved my grade)
Great video
Just amazing
Very well explained. After searching through a lot videos , I finally understood how a resistor resists the current. There are numerous videos explaining what do resistors do but not how they do it. Thank you!!!
This is a good tutorial. Though, will need to watch again to really understand capacitors. This is where I get slightly confused.
Robert Hopkins he went a little too fast with the examples. but putting the speed down a bit helps when rewatching
Nice speech..realy helpfull
Clear as mud. Guess I should find an earlier video explaining some of the terms.
very good video
Where can we get the software you used to illustrate every section?
Thanks it make me a bit easy to learning
EXCELLENT
THANK YOU!!!! :D
What program do you use to make that animation possible at 4:50 ?
quality teaching
Wow very good...
Hey!
Thanks a lot.
Excellant.
What a great anatomy
Can I ask a question want to make my own 12v led torch using capacitors and resistors want no which capacitor and resistor ohm is best for storing energy fast with very low discharge rate want to make my own storage module using capacitors instead of batteries thank you
Helpfull.
very nice God bless
what two types of reactions are enzymes involved in?
Loads of Love from INDIA
thanks a lot
Great video thanks. Now, how, where and why do we use resistors and capacitors. Especially capacitors
Electrical engineering mainly. They’re used to make rechargeable batteries in your phone and stuff I believe
short and sweet
Thank you
What simulation is this
the best!
super thank you
Awesome
thank you
tell me about the software you are using
+Bozeman Science if i had two capacitors that were 2200 volts and 1.0 uf what would the output in volts and the output in joules and coulombs be? I really need to know plz respond asap!!!!!!!!!
Hi Mr. Anderson !! I have chosen to do an Internal Assessment on resistivity for the IB in Physics and I would love to use the simulator on 4:49 . So please, could you tell me where have you found it?
Found it !! Thank you anyways
Hi Carlos, could you tell me please where have you found it? I am really needing that simulator please!
Eduardo Guevara sure!! It is called RESISTANCE IN A WIRE from phet.colorado.edu
Holy crap you are awesome! Find a way for me to send you money...you've saved me ages of textbook study!
I = V/R very useful formula
if you connect an LED directly to a battery are you just effectively shorting the circuit?
+micheals1992 LED's are not ohmic loads, so they don't obey ohms law. In reality the LED will burnout if you go over its power rating which is why resistors are used in LED circuits.
Mr Anderson Capacitors vs Batteries please
This is amazing! But oh man . I am lost at capacitor :P haha. I will get it !
Great
great vid for a crossover
after hearing this..one thing to come in mind..
only one question to ask..
what on earth the rest 10 videos ive seen were made for if they cant explain capacitors.😑😑😑
The explanation is indeed beautiful but the problem I've found is that the concerned topic is not discussed in details. Sir Anderson has put a very little light on the combinations of resistor and capacitor. Resistor and capacitor and insertion of dielectric could be a separate topic.
what is dielectric a video on that too ..mister andreson
The short answer is: it's the insulator between the capacitor plates, that increases the capacitance from what it otherwise would be, if the gap were empty space.
It's called a dielectric, because the capacitor polarizes its dipoles, that produce an electric field to oppose the electric field of the capacitor plates. This means it takes more charge at the same voltage, since you need more charge to generate the same net electric field inside the dielectric material.
You are using the term "indirect difference" shouldn't the word be "inverse"?
I have a doubt. a resistor restricts the current or voltage in the circuit.?
It resist the flow of electrons which is called current
woooowww😎😎
Hei: Mr, Your explanation of Capacitors Block DC & Allow AC flow is very Brief. Basically AC electron flow simply travel forwards & backwards cycle in between Capacitor Dielectric inside.
You did now explain Why & how first order Crossover Speaker Capacitor can filter & allow AC electron current to flow/pass through Dielectric insulator. Please provide UA-cam video proof & explain in deatail files if you knows. How it works? Tks...
Why AC current pass through Dielectric Capacitor still can Produce sound on Speaker. Why?
cool
example of a tube wel is interesting.......amd.
I love youuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
how work capacitor plz animated video theory
Your analogy suggests that a resistor increases current since the pipe size becomes smaller making water move faster which is current. Just saying...
The pipe size may make water move faster in terms of flow velocity, but it is still the same total amount of kilograms per second of water current that is flowing. And the kg/s is what is analogous to current, not the flow velocity. The change in flow velocity from change in geometry, is a consequence of continuity of mass conservation.
What really forms the analogy of resistance, is the frictional losses that occur due to sudden changes in the geometry of a pipeline, and viscous losses.
You could be Mr Carlson´s brother!
i don't find you on Facebook
you didn't explain the reason for the use of capacitors like you did for resistors
