Concept explainers

Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.

In a circuit consisting of a 9 V battery, about 20 cm of 12-gauge copper wire, and a 60 W light bulb, which of the following correctly describes the motion of charge in the wire? a. The protons move from their initial position in the wire away from the negative terminal of the battery toward the positive terminal of the battery. It would take a proton a short time to travel between the terminals - only a few microseconds. b. The protons are generated in the battery and then move away from the positive terminal of the battery toward the negative terminal of the battery. It would take a proton a long time to travel between the terminals - at least an hour. c. The free electrons move from their initial position in the wire away from the negative terminal of the battery toward the positive terminal of the battery. It would take a free electron a long time to travel between the terminals - at least an hour.
