The most common full form of AC is Alternating Current.
Understanding Alternating Current (AC)
Alternating current (AC) is a type of electrical current where the direction of electron flow periodically reverses. This is in contrast to direct current (DC), where the flow is unidirectional. AC is the standard for delivering electricity to homes and businesses worldwide. The frequency of this reversal is usually 50 Hz (cycles per second) in Europe and 60 Hz in North America. https://ec.europa.eu/health/scientific_committees/opinions_layman/en/electromagnetic-fields/glossary/abc/alternating-current.htm https://byjus.com/physics/difference-between-ac-and-dc/ https://unacademy.com/content/jee/full-forms/ac-full-form/
