What is the primary purpose of using a voltmeter?

To measure current
To measure resistance
To measure voltage
To check battery capacity

The correct answer is: To measure voltage

The primary purpose of using a voltmeter is to measure voltage. A voltmeter is specifically designed to measure the potential difference between two points in an electrical circuit. Voltage is a critical parameter in electrical systems, as it indicates the amount of electrical energy available to drive current through a circuit. Understanding voltage levels can help technicians diagnose issues, assess the health of electrical components, and ensure that systems are operating within safe and efficient parameters. For instance, if a voltmeter indicates a voltage that is too low or too high, it can point toward wiring problems, faulty components, or issues with power supply.
