Ten coulombs of charge start from the negative terminal of a battery, flow through the battery and then leave the positive terminal through a wire, flow through a resistor, and then return to the starting point on this closed circuit. In this complete process, the ten coulombs:
A) receive heat energy from the resistor.
B) do positive work on the battery.
C) have a net loss of potential energy.
D) have no net change in potential energy.
