The potential difference between two points is measured by a voltmeter.

A voltmeter is connected in parallel with the two points across which the potential difference (voltage) is to be measured. It provides a reading in volts (V) and ideally has very high resistance to minimize current draw and avoid altering the circuit behavior.

Hii,

The potential difference between two points is measured by a device called a voltmeter . It tells us how much energy is used to move electric charges between those two points. Just like a thermometer measures temperature, a voltmeter measures voltage.

The unit of potential difference is volt (V) . It helps us understand how strong the electric push is in a circuit.
