RL and RC Series Circuits

A bulb and a capacitor are connected in series across an ac supply. A dielectric is then placed between the plates of the capacitor. The glow of the bulb:

Show answer and solution

Answer: (c)

A dielectric increases $C$ ( $C = K C_0$ ).
$X_C = \frac{1}{\omega C}$ decreases, so impedance falls and current rises.
So the answer is (c) the glow increases.
