Question:

In the figure, if A & B are identical bulbs, which bulb glows brighter?

Show Hint

Inductive reactance increases with frequency, while capacitive reactance decreases with frequency.

The Correct Option is A

Solution and Explanation

The circuit consists of an inductor in series with bulb A and a capacitor in series with bulb B.
- At low frequencies, the capacitor has high reactance, reducing current in bulb B.
- The inductor has low reactance, allowing more current through bulb A.
Since more current flows through A, it glows brighter.
Thus, the correct answer is A.
