Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR.

Answer:
Ohm’s law states that the current (I) flowing through a conductor is directly proportional to the potential difference (V) across the ends of a conductor, provided physical conditions of the conductor such as temperature, mechanical strain etc. are kept constant.
V ∝ I
