potential, electric

potential, electric,

work per unit of electric charge expended in moving a charged body from a reference point to any given point in an electric fieldfield,
in physics, region throughout which a force may be exerted; examples are the gravitational, electric, and magnetic fields that surround, respectively, masses, electric charges, and magnets. The field concept was developed by M.
