In the given diagram, two switches `S_1` and `S_2` and two bulbs X and Y are connected as shown. If switch `S_(1)` is closed and switch `S_2` is open then

A

Only bulb X will glow

B

Only bulb Y will glow

C

Both bulbs X and Y will glow

D

Neither bulb X nor bulb Y will glow.

Text Solution

Verified by Experts

The correct Answer is:
B
Since switch `S_2` is open and `S_1` is closed, the current will pass through Y. But for bulb X, the circuit is incomplete and there is no complete path for current to flow for bulb X. Hence, only bulb Y will glow.
