Ohm’s Law Definition. Ohm’s law states that the current in an electric circuit is proportional to the applied voltage and inversely proportional to its resistance. As the voltage increases in a circuit (resistance remaining constant), the current increases by the same amount. Hence, if the voltage is doubled, the current will double.
