State Ohm's law.
(N/A) Ohm's law states that the electric current flowing through a metallic conductor is directly proportional to the potential difference $(V)$ applied across its ends,provided that its physical conditions,such as temperature,remain constant.
Mathematically,this is expressed as $V \propto I$ or $V = IR$,where $R$ is the constant of proportionality known as resistance.
