Alternating Current
Alternating Current (AC) is an electrical current that periodically reverses direction, in contrast to Direct Current (DC) which flows only in one direction. In aviation, AC is used to power most of the aircraft's electrical systems, including lighting, avionics, and other critical components. AC power is generated by the aircraft's alternator, which converts mechanical energy from the engine into electrical energy. The AC power is then distributed throughout the aircraft via a complex network of wires and circuit breakers. AC power is preferred over DC power in aviation due to its ability to be easily transformed into different voltages, making it more versatile and efficient for powering various electrical systems.
