For the measurement of potential difference, voltmeter is connected

in parallel with the circuit

in open circuit

in series with the circuit

beyond the circuit

Uses a long wire

Works on the principle of wheatstone bridge

Does not disturb the potential difference under measurement

Uses a battery of larger emf in the main circuit

potentiometer has high resistance

potentiometer has low resistance

potentiometer does not draw any current from the unknown source of emf to be measured

potentiometer has greater size than voltmeter
