MHT CET Physics question

Potentiometer is better for measuring the potential difference than the voltmeter because

(A)It uses a long wire
(B)It uses an auxiliary battery of large e.m.f.
(C)It does not disturb the potential difference to be measuredCorrect
(D)It is based on the principle of Wheatstone bridge

Answer: (C)

Solution

At the balance point a potentiometer draws no current from the source, so the potential difference is not disturbed, whereas a voltmeter draws some current; the
