An electric potential is the amount of electric potential energy that a unitary point electric charge would have if located at any point in space, and is equal to the . Current ElectricityBufretLignendeOversett denne sidenIn the previous section of Lesson it was reasoned that the movement of a positive test charge within an electric field is accompanied by changes in potential . Introduction to electric potential energy. Electric potential energy, electric potential, and voltage. David explains electric potential (voltage).
Potential energy can be defined as the capacity for doing work which arises from position or configuration. In the electrical case, a charge will exert a force on .
The unit of electrostatic potential is the volt (V), and V = J/C = Nm/C. Equation (2) shows that as the unit of the electric field we can also use V/m. Describes what would happen to a charge if it was placed in the electric field.
Electric potential, the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. Similarly, there is an electric potential energy associated with interacting charges. For each pair of interacting charges, the potential energy is .
