Q.
Two condensers, one of capacity $C$ and the other of capacity $C/2,$ are connected to a $V$-volt battery, as shown
The work done in charging fully both the condensers is
A) $2CV^{2}$
B) $\frac{1}{4}CV^{2}$
C) $\frac{3}{4}CV^{2}$
D) $\frac{1}{2}CV^{2}$
Explanation
(c) Work done $= \frac{1}{2}\left( \frac{3C}{2} \right).V^{2} = \frac{3CV^{2}}{4}$
