AC Circuits

Question

A bulb and a capacitor are in series with an ac source. On increasing frequency how will glow of the bulb change

Moderate

A

The glow decreases
B

The glow increases
C

The glow remain the same
D

The bulb quenches

Solution

This is because, when frequency v is increased, the capacitive reactance $X_{C} = \frac{1}{2 πνC}$ decreases and hence the current through the bulb increases.
