Physics - EMI/AC Question with Solution | TestHub

The circuit shown in the figure contains an inductor $L$, a capacitor $C_0$, a resistor $R_0$ and an ideal battery. The circuit also contains two keys ${\mathrm{K}}_1$ and ${\mathrm{K}}_2$. Initially, both the keys are open and there is no charge on the capacitor. At an instant, key ${\mathrm{K}}_1$ is closed and immediately after this the current in $R_0$ is found to be $I_1$. After a long time, the current attains a steady state value $I_2$. Thereafter, ${\mathrm{K}}_2$ is closed and simultaneously ${\mathrm{K}}_1$ is opened and the voltage across $C_0$ oscillates with amplitude $V_0$ and angular frequency ${\omega }_0$.
