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

A

$CV$

B

$\frac{1}{2}\,nC{V^2}$

C

$CV^2$

D

$\frac{1}{{2n}}\,C{V^2}$

Solution

Equivalent capacitance of parallel combination

${\mathrm{E}_{\mathrm{eq}}=\mathrm{nC}} $

$\therefore $ energy stored $ \mathrm{U}=\frac{1}{2} \mathrm{C}_{\mathrm{eq}} \mathrm{V}^{2}$

${=\frac{1}{2}(\mathrm{nC}) \mathrm{V}^{2}}$
