voltmeter is a device to measure
 A power B current C potential difference D resistance
Explanation:

Detailed explanation-1: -A voltmeter, is an instrument used for measuring the potential difference, or voltage, between two points in an electrical or electronic circuit. It is connected with the circuit always in parallel to measure voltage.

Detailed explanation-2: -A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog to digital converter.

Detailed explanation-3: -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-4: -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). Many voltmeters are digital, giving readings as numerical displays.
