Assertion : In the given circuit if lamp `B` or `C` fuses then light emitted by lamp `A` decrease.
Reason : Voltage on `A` decreases.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
When lamp B or C gets fused equivalent resistance of B and C increases. In series voltage distributes in the ratio of resistance, so voltage appearing across B increases or in other words voltage across A decreases.
