PhysicsEasysingle choice

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

Options:

Answer:

Solution:

The two condensers are in parallel. Their equivalent capacitance is $C_{e} = C + \frac{C}{2} = \frac{3 C}{2}$ The formula for work done is $W = \frac{1}{2} C_{e} V^{2} W = \frac{1}{2} (\frac{3 C}{2}) V^{2} W = \frac{3}{4} CV^{2}$
