If there is no change in the physical condition of a conductor such as temperature etc., then the potential difference applied at the ends of the conductor is directly proportional to the current flowing through it. This law is

The law stating that the potential difference applied at the ends of a conductor is directly proportional to the current flowing through it, given no change in the physical condition of the conductor, is Ohm’s law. This law defines the linear relationship between voltage, current, and resistance in electrical circuits.
