Question:
In the figure, if A & B are identical bulbs, which bulb glows brighter?
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.
Updated On: Mar 19, 2025
- A
- B
- Both with equal brightness
- Both do not glow
Hide Solution
Verified By Collegedunia
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.
- 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.
