what is capacitor?
A capacitor is a devise to store charge.alternatively,it is possible to think of a capacitor as a device for storing electrical energy.
After all, the charge on the plate possesses electrical potential energy which arises because work is to be done to deposit charge on the plates.this is due to the fact that with each small increment of charge being deposited during the charging process, the potential difference between the plates increases, and a larger amount of work is needed to bring up next increment of charge.
initially when the capacitor is uncharged, the potential difference between plates is zero and finally it becomes "v" when q charge is deposited on each plate.thus the average potential difference is give below..

Therefore P.E is below ...
Using the relation q = CV for for capacitor we get
