Boundary Conditions for Current Density
Description
Current density becomes discontinuous across an interface of materials with different electrical conductivities. The normal component of the current density is continuous across the boundary.

The current density becomes discontinuous across an interface having different electrical conductivities.
For steady currents, the divergence of the current density is zero. So, the normal component of the current density is continuous across the boundary.
Recall that the tangential component of the electric field is continuous acr...
