Question

Distinguish between potentiometer and voltmeter.

✓

Answer

	Potentiometer	Voltmeter
1.	The emf of a cell, potential difference, and internal resistance are all measured with a potentiometer.	A voltmeter can be used to determine a cell's potential difference and terminal voltage. However, it cannot be used to measure the emf of a cell.
2.	It has a high level of accuracy and sensitivity.	Its accuracy and sensitivity are less as compared to a potentiometer.
3.	It is not a portable instrument.	It is a portable instrument.
4.	It does not give a direct reading.	It gives a direct reading.
