Answer to Question #178708 in Electric Circuits for Edna

Question

It takes 50J of energy to move 10C of charge from point A to point B. What is the potential difference between points A and B

Answer 1

By definition, potential difference VV between points A and B is work required to move a charge from point A to point B per unit charge:

$V=\frac {W} {q} =\frac {50}{10}=5V$
