Work done by battery is =QV Stored energy is capacitor =(1/2)QV % stored energy =50

Q. How many percent of work done by a battery is consumed to fully charge a capacitor which is stored as electric potential energy in the capacitor?

$25$

$50$

$70$

$100$

Work done by battery is $= Q V$
Stored energy is capacitor $= \frac{1}{2} Q V$
% stored energy $= 50$
