How To Calculate The Energy Stored In a Capacitor

This physics video tutorial explains how to calculate the energy stored in a capacitor using three different formulas. It also explains how to calculate the power delivered by a capacitor as well as the capacitance and voltage of a capacitor. This tutorial contains many practice problems on calculating the potential energy stored in capacitors.

man... is there something this guy doesn't know?? we appreciate you!

[COMPUTERSARAY]

i didn't expect it to be this simple !! thanks man hope i get good grade in this physics exam

[AshishPariyar-ej]

You make students feel the concept and make easy understanding for numerical thank you so much.

[armitahesari]

This channel is taking me through med School thanks

[kneelherbz]

in no.4 you can also get the capacitance first by using U=1/2 (x)V^2 then you get 0.5F, after you got the Capacitance you can apply it in U=1/2(0.5F)(20V)^2 and still get an answer of 100J

Thank you, this has been very interesting.

I'm confused with how you get Electric potential energy because I thought you could do Ue = Vq so multiply the charge of the capacitor by the electric potential. When I do this, I get a different answer than when I do 1/2CV^2.

[saransh]

I was trying to look for energy in capacitors involving circuit diagrams because those are given in my book

[betelihemm.]

You are the best! I don't know why the 2 dislikes are there.

[hanon]

This has helped me alot thank you so much.

[pepperjack]

Very good. You made it simple. That very talented of you.

[ghopikrishnaa]

👌👌👌👍👍 I'm happy to see your concepts..it's really useful for students like me(waste)

A battery of 20 V is connected across a pair of capacitors of capacitance

4uF and 6mu*F connected in series. Calculate:

a) The potential difference across each capacito

b)The total energy
How to solve the problem 😒😌

[ironforged]

That Formula in the Thumbnail, *U=½Q²/C*

How was that derived? Kindly explain...

[kelvinmark]

In the last question, I don't seem to understand where the x10^-6 came from. Pls help

[PraxZimmerman]

I have no idea how you're deriving that equation from the si units

[jriyxrm]

Do I need to convert ng pF to F first?

[hellothere]

how is farad times volts^2 equal to Joules?

[tomas_soeterik]

where does that formula come from ? I can't seem to find it

[Bodragon]

It's "KOO-LOM" not "KUH-LOOM"
