Alternating Current theory

Alternating Current (AC) is a type of electrical current that periodically reverses direction, unlike Direct Current (DC), which flows steadily in one direction. AC is commonly used in homes and businesses because it can be easily transformed to different voltages, making it efficient for long-distance transmission. The frequency of AC, measured in hertz (Hz), indicates how many times it changes direction per second; for example, in the U.S., the standard frequency is 60 Hz. AC allows for the use of devices like transformers and motors, facilitating a reliable supply of electricity for various applications.
