Maxwell developed the time-varying form of Ampere's law by adding the term, such that V x B=uJ+
Addition of this term makes the differential form of Ampere's law consistent with the equation of , which is given as v.j=
To simplify Maxwell's equations, we use the potential functions A and V, and the fact that the potential function for a given magnetic or electric field is not unique. In time-varying field, using the Faraday's law, the electric field can be expressed in terms of A and V as,
E =
Applying the above equation to the Ampere's law, with the choice of divergence of A as
V.A:
we can uncouple the wave equations for A and V from the Maxwell's equations
