Solution

The correct option is B $\frac{1}{2} n C V^{2}$
Energy stored in each capacitor $= \frac{1}{2} C V^{2}$
$∴$ energy stored in n capacitors $= \frac{1}{2} n C V^{2}$

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

The correct option is B 12nCV2Energy stored in each capacitor =12CV2∴ energy stored in n capacitors =12nCV2

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

The correct option is B $\frac{1}{2} n C V^{2}$
Energy stored in each capacitor $= \frac{1}{2} C V^{2}$
$∴$ energy stored in n capacitors $= \frac{1}{2} n C V^{2}$
