The presence of an electric field and the accompanying force means that motion of charged bodies within this field involves work and changes in energy. The possible changes in energy are described by the electric potential. |
|
The electric potential is defined as the energy, or work per unit of charge required to move a charged particle within an electric field, so that
P :: electric potential
E:: Electrical field. This is the force on a charged body due to the electrical field, given in Newtons
d:: Distance through which the body is moved perpendicular to the electric field.
|
P = E * d |

This will be connected to other areas of science, personal studies, anthropology, culture, social institutions, sociology, and history as the site develops further. |
