In the given circuit, find the heat generated if switch $S$ is closed.

In the given circuit, find the heat generated if switch $S$ is closed.
  1. $\frac{3}{2} C V^{2}$
  2. $\frac{1}{2} C V^{2}$
  3. $C V^{2}$
  4. $\frac{1}{3} C V^{2}$

Solution

$\begin{array}{l}
C_{\mathrm{eq}}=C\\
\text { So, work done by battery }=C V^{2}\\
\text { Heat generated }=\frac{1}{2} C V^{2}
\end{array}$ undefined
