RL and RC Series Circuits

A light bulb connected in series with a capacitor and an a.c.source is glowing with certain brightness. On reducing the value of capacitance and frequency respectively, the brightness of the bulb

Show answer and solution

Answer: (a)

$X_C = \frac{1}{2\pi f C}$ : reducing either $C$ or $f$ increases $X_C$ .
Larger $X_C$ means larger impedance, smaller current, dimmer bulb in both cases.
So the answer is (a) is reduced, is reduced.
