Question

STATEMENT-1 In a Meter Bridge experiment, null point for an unknown resistance is measured. Now, the unknown resistance is put inside an enclosure maintained at a higher temperature. The null point can be obtained at the same point as before by decreasing the value of the standard resistance. and
STATEMENT-2 Resistance of a metal increases with increase in temperature.

Select the correct option:

A

STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is a correct explanation for STATEMENT-1

B

STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is NOT a correct explanation for STATEMENT-1

C

STATEMENT -1 is True, STATEMENT-2 is False

D

STATEMENT -1 is False, STATEMENT-2 is True

✓ Correct! Well done.
