The potentiometer is preferred over voltmeter when there is a measurement of emf of the cell because the potentiometer does not draw any current as it is a null device. ... This is the reason why potentiometer is preferred over voltmeter in order to get the actual measurement of emf.
Why potentiometer is superior than voltmeter?
While a voltmeter draws a small current from the cell for its operation.So it measures the terminal p.d. in a closed circuit which is less than the emf of a cell. That is why a potentiometer is preferred over a voltmeter for measuring the emf of a cell.
Why it is better to use potentiometer over voltmeter?
The advantage of a potentiometer over the voltmeter is that the potentiometer doesn't draw any current from the circuit in which it is used for the measurement. Whereas the voltmeter draws some amount of current in case of high voltages, which results in some errors in the measurements done using a voltmeter.
