Physics Alternating Current MHT CET 2026

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

(A)is reduced, is reducedCorrect
(B)is more, is more
(C)is more, is reduced
(D)is reduced, is more

Answer: (A)

Solution

In the series circuit the capacitive reactance is and the impedance is . The brightness of the bulb depends on the rms current . Reducing the capacitance increases , so increases and decreases, and the bulb
