Question

what is the relationship between potential difference and direction of flow of current in an electric circuit

Answer 1

potential difference is directly proportional to current
means vis directly proportional to i

Answer 2

Answer:

The difference between the values of potentials at two points A and B is called the potential difference between them. In the figure, conductor A is at a higher potential than conductor B. When these two are connected by a conducting wire, a potential difference is created between its two ends and electrons will flow from B to A through the wire. This flow will continue until the two conductors, A and B have the same potential, i.e. until their potential difference becomes zero. Only then will the flow of electrons stop.

Work has to be done against the electric field to take a positive charge from a point of lower potential to a point of higher potential.
