Energy potential difference formula
WebNov 24, 2024 · Potential Difference Formula. The amount of work (W) done by an external agent in transporting a unit charge (Q) from one point to another is defined as the potential difference between two points (E) in an electrical circuit. The formula for calculating the potential difference is as follows: E = W/Q. Here, Potential difference is denoted as E, WebThe change in potential energy, Δ PE, is crucial, since the work done by a conservative force is the negative of the change in potential energy; that is, W = –Δ PE. For example, …
