Explanation:
Detailed explanation-1: -A voltmeter is a device which is used to measure potential difference between two points in a circuit. Potential difference is measured in voltage, hence the name is voltmeter. Voltmeter is connected in parallel in a circuit.
Detailed explanation-2: -voltmeter, instrument that measures voltages of either direct or alternating electric current on a scale usually graduated in volts, millivolts (0.001 volt), or kilovolts (1, 000 volts).
