Alternating Current Generators, or AC generators, are devices that convert mechanical energy into electrical energy in the form of alternating current. They work on the principle of electromagnetic induction, where a conductor, such as a coil of wire, rotates within a magnetic field. This rotation induces an electric current that alternates direction, hence the name. These generators are widely used in power plants and various applications due to their efficiency in producing electricity. The generated AC can be easily transformed to different voltage levels, making it suitable for long-distance transmission and distribution to homes and businesses.
