It is clear that the potential difference is necessary for flow of current.
Greater is the potential difference greater will be the current.
Thus there is it distinct proportion between potential difference and current.
This relation is nothing but ohm law.
Ohm's law state that, at constant temperaturethe potential difference across the end of the conductor is directly proportional current flowing through it.

let a potential difference V be applied across the end of the conductor and I be the current flowing through it then,

V is directly proportional to I

provided temperature of conductor remaining constant.

V = R × I

Where R is the constant of proportional known as Resistivity of the conductor.
