Question

Find the relation between current density and electric field

Answer 1

Electric fields cause charges to move. It stands to reason that an electric field applied to some material will cause currents to flow in that material. For an amazingly wide range of materials, an empirical rule called Ohm's law gives the following relation between current density and applied electric field: J = σ E .
