Hi Ankitshyani! Welcome to PF! :wink:

(have a mu: µ :wink:)

What is the usual formula for energy of a capacitor?

Show us how far you get, and where you're stuck, and then we'll know how to help! :smile:
 
hi there,

how are you...the formula for energy stored in the capacitor is: W = 1/2 C V ...

thanksss

No, CV is the charge of a capacitor …

go back to your book and study it again. :wink:
