Which device is used to measure electrical potential or voltage?

• A. Ammeter
• B. Ohmmeter
• C. Voltmeter
• D. Wattmeter

Answer: (C)

The device used to measure electrical potential or voltage is the voltmeter. It is specifically designed to measure the potential difference between two points in an electrical circuit. When you connect a voltmeter across a component or section of a circuit, it provides a reading that indicates the voltage present, usually expressed in volts. This measurement is critical for diagnosing and troubleshooting electrical systems, as voltage levels can affect the performance and operation of electrical devices. In contrast, an ammeter measures the flow of electric current in a circuit, an ohmmeter assesses the resistance of a component, and a wattmeter measures the power consumption in terms of watts. Each of these devices serves a distinct purpose, making the voltmeter the appropriate choice for measuring voltage.
