7.3: Electric Potential and Potential Difference - Physics LibreTexts

The electric potential at a point r in a static electric field E is given by the line integral where C is an arbitrary path from some fixed reference point to r. In electrostatics, the Maxwell-Faraday equation reveals that the curl is zero, making the electric field conservative. Thus, the line integral above does not depend on the specific path C chosen but only on its endpoints, making well-defined everywhere. The gradient theorem then allows us to write: Webq is the symbol used to represent charge, while n is a positive or negative integer, and e is the electronic charge, 1.60 x 10-19Coulombs. The Law of Conservation of Charge The Law of conservation of charge states that the net charge of … WebSep 12, 2024 · Electric Potential Difference. The electric potential difference between points A and B, VB − VA is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. 1V = 1J / C. bringing old photo back to life
