Ohms law

From Biology-Online Dictionary | Biology-Online Dictionary

ohm's law

(Science: physics) 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.
