What are the disadvantages of a potentiometer?

✓

Answer

Disadvantages of a potentiometer over a voltmeter :

The use of a potentiometer is an indirect measurement method while a voltmeter is a direct reading instrument.
A potentiometer is unwieldy while a voltmeter is portable.
Unlike a voltmeter, the use of a potentiometer in measuring an unknown emf requires a standard . source of emf and calibration.
