Assertion : The e.m.f. of the drivercell in the potentiometer experiment should be greater than the e.m.f. of the cell to determined.

Options

A. Statement `1` is true, Statement `2`is True , Statement `2` is correct explanation for Statement `1`.
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.

Answer

A

Explanation

If either the emf of the driver cell or the potential difference across the whole potentiometer wire is lesser than the emf of the experimental cell, the balance point will not be obtained.
