The instrument used to measure Potential Difference in an Electrical Circuit is called a Voltmeter. A voltmeter is designed specifically to measure the voltage, or electric potential difference, between two points in an electrical circuit. It is connected in parallel to the component or circuit section where the voltage needs to be measured. By using a voltmeter, technicians can diagnose issues, determine whether devices are receiving adequate voltage, and ensure that electrical systems are functioning as intended.

Understanding the function of a voltmeter in measuring potential difference is fundamental in electrical work, particularly for anyone pursuing a Gas Technician 2 (G2) License, as it ties into the safety and efficient operation of gas systems that depend on electrical components.
