The accurate measuremetn of emf can be obtained using

A

multimeter

B

voltmeter

C

voltameter

D

potentiometer.

Text Solution

Verified by Experts

The correct Answer is:
D
A potentiometer does not draw any current from the cell whose emf is to be measured, whereas a voltmeter always draws some current. Hence we can measure the emf of a cell accurately by using a potentiometer.
