How is potential difference measured
Web29 mrt. 2024 · Potential difference must be measured between two points because it is generally impractical to measure the electrical potential of a single point. The potential difference of a point in an electrical circuit is typically made with respect to a reference potential, such as the common ground. WebThe electric potential difference between points A and B, V B − V A, is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. …
