What does “AC” stand for in electrical terms?

In electrical terms, "AC" stands for Alternating Current. This term refers to the flow of electric charge that periodically reverses direction, as opposed to direct current (DC), where the flow of electricity is in a single direction. Alternating current is widely used for power distribution in homes and businesses because it can be easily transformed to different voltages. This adaptability is advantageous for transmitting electricity over long distances, as it minimizes the energy lost during transmission.

The significance of AC lies in its ability to power various appliances and equipment more efficiently compared to other forms of current. Additionally, the design of electrical systems and devices is often based on the properties and behavior of alternating current. Understanding AC is fundamental for anyone working in electronics and electrical engineering.
