Work of `14J` is done to move `2C` charge between two points on a conducting wire. What is the potential difference between the two points ?

How is potential difference between two points expressed?

The work done in moving a charge of 3 C between two points is 6J. What is the potential difference between the two points?

5 J of work is done in moving a positive charge of 0.5C between two points. What is the potential difference between these points ?

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

Calculate the work done to move 500 xx 10^(18) , electrons between two points in an electric field where the potential difference between the two point is 1 millivolt (e = 1.6 xx 10^(-19)C)
