Ohm''s law states that the current through a conductor between two points is directly proprtional to the potential difference across the two points.

At constant physical conditions,the potential difference across 2 pts of a conductor is directly proportional to the current flowing through it.

mathematically, V=IR

where R is the conatant of proportionality known as the resistance of the wire between the two ends.

Ohm`s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: I = rac{V}{R}, where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm`s law states that the R in this relation is constant, independent of the current
