A voltmeter that is being used to measure a voltage drop across a resistor is most like which of the following?
A) A differential pressure gauge measuring the pressure drop across a hydraulic circuit restriction
B) A flow meter measuring the rate of hydraulic fluid flow
C) Two pressure gauges measuring the pressure in a hydraulic circuit referenced to atmospheric pressure
D) An ohmmeter measuring the resistance in an electric circuit with current flowing through the circuit

Question

Quizplus · Accepted Answer

A voltmeter measures the difference in electric potential between two points, similar to how a differential pressure gauge measures the pressure difference across a restriction.
