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:
Answer: (A) increases
The dielectric increases $C$, which lowers $X_C = \dfrac{1}{\omega C}$. The impedance falls, the current rises and the bulb glows brighter.
