Assertion : In practical application, power rating of resistance is not important.
Reason : Property of resistance remains same even at high temperature.

A

Both A and R are true and R is the correct explanation of A

B

Both A and R are true but R is NOT the correct explanation of A

C

A is true but R is false

D

A is false and R is true

Text Solution

Verified by Experts

The correct Answer is:
D
Power rating describes the heat dissipation capability of the resistor. If the heat generated is more than the power rating of the resistor, it will burn. So assertion is false. Resistance value is temperature dependent. So, the reason is true, But reason does not explain the assertion.
