Question

how is potential difference of a conductor related with current?

Answer 1

HEY MATE!!
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points. Potential difference is the work done in moving a unit of positive electric charge from one point to another.

Answer 2

The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R. 2. ... An increase of potential energy in a circuit causes a charge to move from a lower to a higher potential (ie.
