Question

derive an expression for energy store in a capictor answer me of 5matks




​

Answer 1

Hey

Let us consider a capacitor of capacitance C and potential difference V between the plates.

Let the charge on one plate be +q and -q on the other.

Suppose the capacitor is being charged gradually.

Now,at any stage the charge on capacitor is q.

( In the pic)

The energy is stored in the form of potential energy.

hope this helps

pls mark my answer as brainliest plzzzzzzz

thank you

Answer 2

Therefore, the potential difference = Cq.

Small amount of work doe in giving n additional charge dq to the capacitor is. dW= Cq∗dq.

W = CQ2.
