B

Statement `1` is True, Statement `2` is True, Statement `2` is NOT a correct explantion for Statement `1`.

C

Statement `1` is True, Statement `2` is False.

D

Statement `1` is False, Satement `2` is True.

Text Solution

Verified by Experts

The correct Answer is:
A
In a balanced condition, the potentiomaeter does not draw any current, anf hence does not disturb the circuit.
