Question
A battery is used to charge a parallel plate capacitor till the potential difference between the plates becomes equal to the electromotive force of the battery. The ratio of the energy stored in the capacitor and the work done by the battery will be
Options
A.1
B.2
C.

D.

Solution
Work done by battery = Charge flown × Potential difference
(Charge is conserved so charge flown from battery = charge stored in capacitor )
Energy stored in capacitor = 1/2 q × v
