If there are n capacitors in parallel connected to V volt source, then the energy stored is equal to

Options

A $\mathrm{CV}$
B $\frac{1}{2} \mathrm{nCV}^2$
C $\mathrm{CV}^2$
D $\frac{1}{2 n} CV^2$

Correct answer

B. $\frac{1}{2} \mathrm{nCV}^2$

Step-by-step solution

E=\sum \frac{1}{2} C V^2=\frac{1}{2} n C V^2
