What is alternating current?

An electric current flowing in one direction only
An electric current flowing in a circular motion
An electric current flowing first in one direction and then in the opposite direction
A current that does not move

The correct answer is: An electric current flowing first in one direction and then in the opposite direction

An electric current is a flow of electric charge. Alternating current (AC) is a type of electric current that constantly changes its direction of flow. This is in contrast to direct current (DC), which flows in one direction only. Option A, B, and D are all incorrect because they describe either DC or a current that does not flow. Alternating current is used to power our homes and businesses because it can easily be changed into different voltages for various uses.
