Electric charge
... Electric field is the electric force on an imaginary unit positive charge. Electric field lines start or end in electric charges. When fields are strong, electric field lines get closer. Electric field of a single charge is |E|=kq/r2 The “dipole moment” vector p has magnitude qa and direction from – ...
