Electric field strength

Electric field strength (E) is defined as Newtons per Coulomb.

In a uniform electric field, with straight uniformly spaced field lines, the force is constant and the work done in moving a charge q a distance d against the field is Fd. The work done, Fd, is equal to the potential energy gained, Vq.

Rearranging, gives two equivalent definitions of electric field strength...

Electric field strength is expressed as Newtons per Coulomb and/or Volts per meter. The two definitions are equivalent.
