| ASSERTION: A voltmeter and ammeter can be used together to measure resistance but not power. |
| REASON: Resistance and power both are proportional to voltage and current. |
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 :
As \[R=\frac{V}{I}\]and \[P=VI\], by measuring V and I simultaneously in circuit we can measure both resistance and power, using the given relation. But resistance is not a function current. Therefore, reason given is wrong.
