A series $R-C$ circuit is connected to $AC$ voltage source. Consider two cases; $(A)$ when $C$ is without a dielectric medium and $(B)$ when $C$ is filled with dielectric of constant $4$ . The current $I_R$ through the resistor and voltage $V_C$ across the capacitor are compared in the two cases. Which of the following is/are true?

$(A)$ $I_R^A > I_R^B$ $(B)$ $I_R^A < I_R^B$ $(C)$ $V_C^A > V_C^B$ $(D)$ $V_C^A < V_C^B$

A circuit consists of a coil with inductance $L$ and an uncharged capacitor of capacitance $C$. The coil is in a constant uniform magnetic field such that the flux through the coil is $\phi$. At time $t=0 \,min$, the magnetic field is abruptly switched $OFF$. Let $\omega_{0}=1 / \sqrt{L C}$ and ignore the resistance of the circuit.Then,
