alternators

#9. A constant frequency AC supply in an aircraft with only frequency wild generators is provided by:

• Aan inverter.
• Ba diode.
• Can auto-transformer.
• Da rectifier.

#1. An alternator is:

• Aa reversing input switch.
• Ban AC generator.
• Ca DC generator.
• Da static inverter.

#2. AC generators usually have a rotating field and a fixed armature to:

• Areduce the overall diameter of the of the generator.
• Ballow the output to be taken from the stator.
• Creduce the weight of the generator.
• Dprevent arcing at the commutator.
