  Term: Ohm's Law
  Definition: The relationship between the net current and the electric field in a conducting medium. For simple resistors, the voltage equals current times resistance, V = I*R. In plasmas the "generalized Ohm's Law" is a more complex tensor relationship involving the vector current density, the vector for the electric field, and a generalized resistance tensor that relates the two.
