How did alternating current get its name?

Answer 1

AnswerElectricity comes from the Greek root word electra, which means "amber." This comes from an observation made by a Greek philosopher, Thales . As he was polishing a piece of amber with a silk cloth, he noticed that it attracted more dust and hair afterward. Hence the name electricity.

Answer 2

In an alternating-current (AC) circuit, the electrons move through the circuit in one direction for a short period of time, and then move back in the other direction for a like period of time, changing direction at definite intervals. It is this characteristic that gives it its name.

Answer 3

Alternating current got its name because the direction of the flow of electric charge periodically reverses instead of flowing in one consistent direction. This is in contrast to direct current, where the flow of electric charge is always in one direction.
