What does AC stand for in electrical terms?

In electrical terms, AC stands for Alternating Current. This type of electrical current periodically changes direction, in contrast to Direct Current (DC), which flows in a single direction. Alternating Current is widely utilized for powering homes and businesses because it is more efficient for long-distance transmission. The ability of AC to easily change voltage levels using transformers makes it advantageous for electrical grids, allowing for the reduction of energy loss during transmission over extensive distances.

This understanding of AC is fundamental in the field of electrical engineering and technical support, as it impacts how electrical systems are designed, maintained, and understood in real-world applications.
