Where does the engine receive its electrical power?

Explanation:
Electrical power for the engine is produced by the engine-driven alternator. The alternator is driven by the engine’s accessory drive, converting the engine’s mechanical energy into electrical energy to feed the electrical system. Other sources exist, but they aren’t the normal source for the engine’s power: an external power unit is used on the ground, the APU provides power when the engines aren’t running or to augment power, and the aircraft battery supplies starting and emergency power rather than continuous engine electrical power.
