Question

In the diagram, the arrow shows the movement of electric charges through a wire connected to a battery. A battery with an arrow at its top running from left to right. A black line connects the right end of the battery to the left end by making a series of straight lines to form a rectangular box with the battery as part of the bottom side.

What causes the electric charges to flow from one end of the battery to the other?
A. a balance in electric potential
B. a balance in resistance
C. a difference in electric potential
D. a difference in resistance

Answer 1

Answer: A difference in electric potential (voltage)

Explanation: Electric current moves to places with lower potential difference, a difference in electric potential would make the charge move from one end of the battery, around the wire and to the other side.

Answer 2

C. a difference in electric potential
