Question

A bulb and a capacitor are connected in series to a source of alternating current. If its frequency is increased, while keeping the voltage of the source constant, then (A) Bulb will give more intense light (B) Bulb will give less intense light (C) Bulb will give light of same intensity as before (D) Bulb will stop radiating light

When a bulb and a capacitor are connected in series to an AC source, then on increasing the frequency the current in the circuit is increased, because the impedance of the circuit is decreased. So the bulb will give more intense light.

Bulb will give more intense light

Bulb will give less intense light

Bulb will give light of same intensity as before

Bulb will stop radiating light
