Intro to Capacitors | Doc Physics

Super useful things, capacitors. I hope they will be used to run cars within the next twenty years. That's your job, students.

I love teachers who enjoy teaching. Makes learning easier and much more fun.

You teach awesome !!
And you really don't have to change color for + and - ..:D

[michellec.]

I wish my professor was as enthusiastic about teaching physics as you are then maybe the whole class wouldn't fall asleep. I'm discovering how awesome physics really is! thank you

The problem is that water is used as analogy to electricity instead of gas, because water is practically incompressible contrary to gas. A capacitor should bee seen as a gas cylinder instead of a bucket. This way you may do a better analogy, like this:

V = Gas pressure;
Q = Gas quantity;
C = Capacity of Gas storage for a given pressure, and so Q/V.

Like a gas cylinder, greater pressure (V) means that greater quantity (Q) may be stored, however, if you increase V (gas pressure) too much, it blows up, so, besides C a capacitor has also defined the maximum pressure V it can handle before it blows up...
This is why you should think in electricity as Gas flow instead of Water flow.

Okay so I gotta find out what charge density & epselon & edge effect are (pretty sure I don't need to know all of this to be an electrician but love the knowledge). Yet another great sesh. Love your teaching. Please keep it up.

That's just from an old radio, man. The black pulley on the side had a string around it that moved the tuning indicator. Three cheers for manufacturing ingenuity!

Personally, I likes your video. It's easy to understand and yet you are so funny. Keep it up Doc! =)

[hihikasu]

Thx, dude. That is super clear, enjoy your teaching!

[OK-rieu]

this was made back in 2013 wow. I liked how he explained every "Formula" and not just write them down without explaining. Thanks for this very efficient 10 minutes

[LthalShadws]

Bustin a cap! haha man you're awesome

[shivanisathaye]

Thank you for explaining the topic so You are a great Love the way you add a bit of humor in you lectures 👏👏😁😁

[mungy]

i learned more from this 10min video than my 3hr physics course thanks

[yazazan]

The area in the equation - C = (Epslon*A)/d - is the area of overlapping of the plates, correct?

[rorymackinnon]

Do you trip acid? you have godly understanding... I maybe crazy, but I'm watching this video rn on acid, and I've either opened my third eye or I've seen god's matrix

[dantox]

I'm almost sure he is talking about Carnot, such as refrigerators and air conditioners etc.

[kapoioskapoiou]

Great math only if we want to build our own capacitor YOU WILL NEVER USE THEM.

[DijyowLee]

Capacitors are SHOCKINGLY useful.

saw what you did there

[sadneer]

The "C" in the video is heat capacity i thnk..

[sidereal]

You are incredibly informative and entertaining. Great videos!

[mohajeramir]

Great Job. Thank you for all your videos.
