Electric potential energy physics
WebElectric potential is the electric potential energy per unit charge. It is known as voltage in general, represented by V and has unit volt (joule/C). 1C charge is brought to the point A from infinity. Work done here is called potential of q at A. Electric potential is found by the given formula; V=k.q/d V is a scalar quantity. WebMay 27, 2024 · Electric Potential is the outcome of potential difference between two electric sources. The phenomenon of lightning is the best example of Electric Potential. We know from Classical Mechanics that work is done due to potential energy. Electric Potential also does work.
