Two condensers, one of capacity $C$ and the other of capacity $\frac{C}{2}$ , are connected to a $V$ -volt battery, as shown.The work done in charging fully both the condensers is

Options:

Answer:

Solution:

The two condensers in the circuit are in parallel order, hence $C^{'} = C + \frac{C}{2} = \frac{3 C}{2}$ The work done in charging the equivalent capacitor is stored in the form of potential energy. Hence, $W = U = \frac{1}{2} C^{'} V^{2} = \frac{1}{2} (\frac{3 C}{2}) V^{2} = \frac{3}{4} C V^{2}$
