Question

The AC frequency induced into the alternator stator is determined by what factors?

Option 1: The phase of the moon
Option 2: The number of passengers on the aircraft
Option 3: The rotor speed and the number of poles
Option 4: The pilot's skill level

Answer 1

The AC frequency induced into the alternator stator is determined by the rotor speed and the number of poles.

Step-by-step explanation:

The AC frequency induced into the alternator stator is determined by the rotor speed and the number of poles. The rotor speed refers to how fast the rotor of the alternator is rotating, while the number of poles refers to the number of magnetic poles present in the alternator's rotor.

As the rotor speed increases, the frequency of the AC voltage produced by the alternator also increases. Similarly, as the number of poles increases, the frequency also increases.

Therefore, the AC frequency induced into the alternator stator depends on the rotor speed and the number of poles.
