Medical Definition of Ohm's law

1. The relationship between the net current and the electric field in a conducting medium. For simple resistors, the voltage equals current times resistance, V = IR. In plasmas the generalised Ohm's Law is a more complex tensor relationship involving the vector current density, the vector for the electric field, and a generalised resistance tensor that relates the two.
