Work done in charging a capacitor is given by:
- W = 1/2 C V^2
- W = C V^2
- W = 1/2 Q^2 / C
- W = Q^2 / C
Correct answer: W = 1/2 C V^2
Solution
The work done in charging a capacitor is stored as its potential energy, which is given by W = 1/2 C V^2. This is derived from integrating the work done to move charge incrementally onto the capacitor plates.
