Can there be potential difference between two adjacent conductors which carry the same positive charge?

How is potential difference between two points expressed?

Is there any conductor which can be given unlimited charge?

In an electric field the work done in bringing a 2 coulomb charge from infinity to a point a is 10 joules and in bringing the same charge to some another point B is 20 joule find the potential difference between two points A and B what would be the work done if the same charge is brought directly from A to B.

WHat is the direction of force between two parallel conductors carrying current in same direction

WHat is the direction of force between two parallel conductors carrying current in opposite direction?

What is meant by saying that the potential difference between two points is 1 V?

What is the difference between a sheet of charge and a plane conductor having charge?

If the potential difference across the ends of a conductor is 1 volt and the current flowing through the conductor is 1 ampere, the resistance of the conductor?
