What is Alternating Current (AC)? - All About Circuits

WebAC voltage detectors work on the principle of capacitive coupling. To understand this, let's return momentarily to electrical circuit theory and recall how a capacitor works. A capacitor has two conductors or "plates" that are separated by a non-conductor called a dielectric. Webalternating current, abbreviation AC, flow of electric charge that periodically reverses. It starts, say, from zero, grows to a maximum, decreases to zero, reverses, reaches a maximum in the opposite direction, returns again to the original value, and repeats this cycle indefinitely.
