Electric potential difference

Question 1

What is electric potential difference

Answer 1

energy needed to move a unit charge between two points

Question 2

What is the equation for work done

Answer 2

work done = charge multiplied by change in potential difference

Question 3

What is the rule for equipotentials

Answer 3

When a charge is moved along the same equipotential no work is done

Question 4

How can the electric potential difference be found

Answer 4

plotting a graph of electric field strength and distance
area under the graph = electric potential difference
