Igniter B is powered by which power source?

Explanation:
Ignition B is powered from a battery-backed source that provides the AC power the igniter needs. The aircraft battery supplies DC, and an inverter converts that DC into the AC voltage required by the spark plug igniters. This setup ensures Ignition B can function during start or when engine-driven generators aren’t yet available. The AC Essential Bus would come from generators and isn’t the guaranteed source during start, and the IDG or FADEC aren’t power sources for the igniter circuit.
