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

A

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

B

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

C

If assertion is true but reason is false.

D

If assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Because of heat production every resistance has a maximum power rating, the maximum power than can be disspated without overheating the device. When this rating is exceded, heat is produced, due to which resistance may change unpredictably.
