Which instrument would you use to measure electric potential?

• A. Ammeter
• B. Voltmeter
• C. Oscilloscope
• D. Multimeter

Answer: (B)

To measure electric potential, the appropriate instrument to use is a voltmeter. A voltmeter is specifically designed to measure the difference in electric potential, or voltage, between two points in an electrical circuit. It is connected in parallel with the component or section of the circuit where the voltage is being measured, allowing it to provide an accurate reading of the potential difference. While other instruments listed like an ammeter, oscilloscope, and multimeter have their respective functions, they do not focus solely on measuring voltage. An ammeter measures current (the flow of electric charge), an oscilloscope provides a graphical representation of voltage over time (but isn't primarily a measurement tool), and a multimeter can measure voltage, current, and resistance, but it is versatile rather than specialized for measuring electric potential alone. Thus, when the goal is to specifically assess electric potential, the voltmeter is the dedicated instrument to use.
