Assertion: In the following circuit the potential drop across the resistance is zero.

Reason: The given resistance has low value.

A

If both the assertion and reason are true and reason is a true explantion of the assertion.

B

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

C

If the assertion is true but reason false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
Both assertion and reason are true but potential difference across the resistance is zero, because diode is in reverse biasing hence no current flows.
