Question

Quizplus · Accepted Answer

A voltmeter is used to measure the potential difference between two points in a circuit. It is connected across the power source, allowing the technician to measure the voltage present in the circuit. A megohmmeter is used to measure insulation resistance, an analog meter is a general term for a type of meter that uses a needle to display readings, and an ammeter is used to measure current flow in a circuit. None of these would be the best choice for measuring potential difference between two points in a circuit.
