Electrostatic Potential and Capacitance - Result Question 41
43. Energy stored in a capacitor is [2001]
(a) $\frac{1}{2} Q V$
(b) $Q V$
(c) $\frac{1}{Q V}$
(d) $\frac{2}{Q V}$
Show Answer
Answer:
Correct Answer: 43. (a)
Solution:
- (a) Energy stored in capacitor
$ =\frac{1}{2} C V^{2}=\frac{1}{2} \frac{Q}{V} \cdot V^{2} \quad(Q=C V)=\frac{1}{2} Q V $
