A charge of 2.0 C flows onto the plates of a capacitor when it is connected to a 12. V battery. How much work was done in charging this capacitor? E) 0.14 m A) 12, B) 24, C) 21.

Solution

Given

Charge Q=2 uC

Potential difference across capacitor V=12 V

Work done in charging the capacitor is

W=qV =12*2u

W=24 uJ
