AC (Alternating Current) (ප්‍රත්‍යාවර්තක ධාරාව)

In physics, “AC” stands for Alternating Current. Alternating current is an electric current that periodically reverses direction, typically found in electrical power systems and household outlets. It is distinguished from direct current (DC), where the electric charge flows consistently in one direction. AC is commonly used for the distribution of electric power over long distances and is the type of electricity supplied to homes and businesses. The direction of the current in AC changes at regular intervals, usually expressed in hertz (Hz).
