Expression for electric potential
WebElectric potential difference, also known as voltage, is the external work needed to bring a charge from one location to another location in an electric field. Electric potential difference is the change of potential energy experienced by a test charge that has a value of + 1 +1 … Lesson 2: Fields, potential, and voltage. Line of charge. Plane of charge. Proof: … WebNormally, the electric potential is simply called the potential or voltage. The units for the potential are J/C, which are given the name volt (V) after the Italian physicist Alessandro Volta (1745–1827). From the equation , the electric potential a distance r from a point charge is 18.25
