# A charge of 6 C is passing through points A and B on a circuit. If the charge's electric potential changes from 24 J to 21 J, what is the voltage between points A and B?

$500 m V$

#### Explanation:

Voltage (or potential difference) between any 2 points is defined as the work done per unit charge to move a charge between the 2 points.

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

$= \frac{\left(24 - 21\right) J}{6 C}$

$= 0.5 V$
