Positive charge \(q\) from the box of positive particles moves towards the negatively charged particles because oppositely charged particles attract each other. The negative charges are trapped in a box, so they cannot move. Both boxes are connected with a conducting wire.

The movement of positively charged particles creates an electric current \(I\). Electric current is the amount of charge that passes a cross-sectional area of the wire per time.
