Modern aircraft electrical systems act as the "nervous system" of the plane, powering everything from flight instruments and landing gear to critical avionics. In simple general aviation aircraft, systems usually operate on or 28-volt direct current (DC), while commercial jets utilize more complex alternating current (AC) systems, often at 115V and 400Hz , to save weight on components like motors and transformers.

A typical system consists of four primary stages: generation, storage, distribution, and protection. Aircraft electrical systems explained - Facebook
