Question

Work done in charging a capacitor is given by:
Options
A 1/2 QV
Correct Answer
B 2QV
C QV
D 2V
Correct Answer

Option A is the correct answer.

Detailed Explanation

Energy stored/work done in charging a capacitor: W = 1/2 QV (equivalently 1/2 CV2 or Q2/2C), because the voltage rises linearly from 0 to V as charge builds up, giving an average of V/2.
