Fundamental generalization describing the flow of direct current in an electrical circuit, by stating that the magnitude of the current is proportional to the potential difference, provided the resistance is constant. (The unit of potential difference, the volt, has been so chosen that 1 volt is produced across a resistance of 1 ohm when 1 ampere is flowing through it
