Steady Current
... The condition ∇ · j = 0 implies that the lines of current density are like the electric field lines. In some instance, we can define the convection current density as j(r) = ρ(r)υ(r) Current density in many systems obeys Ohm’s law, j = σE. Like P = 0 χE, Ohm’s law is a constitutive relation which ...

If we assume that there is no charge present inside the cavity, the electric field inside the cavity must be zero, regardless of the charge distribution on the outside surface of t ...
