Ohm's Law
■The potential difference (voltage) across an ideal conductor is proportional to the current through it.
■ The constant of proportionality is called the "resistance", R.
■Ohm's Law is given by:
■V = I R
■The current flowing through a conductor is directly proportional to the voltage applied to across the ends of the conductor.
■So, the V-I graph for a conductor following the Ohm’s law is a straight line with a positive slope.

Answer:
The potential difference between two point is directly proportional to the electric current which passes through the given wire,,and inversely proportional to the resistance of wire.
V = I /R
here I is the electric current,and R be the resistance of wire .
