AC (Alternating Current)

Alternating Current (AC) is a type of electrical flow where the direction of the current reverses periodically. Unlike Direct Current (DC), which flows in a single direction, AC's changing flow allows it to efficiently transmit electricity over long distances. This is the standard form used in homes and businesses to power appliances, lights, and devices. The frequency of this reversal is measured in Hertz (Hz); for example, in most countries, AC reverses 50 or 60 times per second. This cyclical nature of AC makes it adaptable for transformers and efficient distribution across power grids.
