| ASSERTION: In practical 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 true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: D
Solution :
Because of heat production every resistance has a maximum power rating, the maximum power that can be dissipated without overheating the device. When this rating exceed heat is produced, due to which resistance may change unpredictable.
