# A charge of 9 C is passing through points A and B on a circuit. If the charge's electric potential changes from 27 J to 3 J, what is the voltage between points A and B?

$2.67 V$

#### Explanation:

Form definition, the voltage or potential difference between any 2 points in an electric field or electric circuit is the work done per unit charge to move a charge between the 2 points.

$\therefore V = \frac{W}{Q}$

$= \frac{27 - 3}{9}$

$= 2.67 V$
