Voltmete: A voltmeter is an instrument used for measuring the electrical potential difference between two points in an electric circuit. A voltmeter is an instrument used to measure the potential difference between the two ends of a current-carrying conductor
Connection of voltmeter
A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.
Final Answer:
To measure the potential difference between two points, the voltmeter is connected to parallel to those points.
