What is one factor that controls the output frequency of an alternator?

A) number of stator poles and rotor rotation speed
B) input voltage
C) number of stator poles and number of rotor bars
D) input voltage and torque

Output Frequency

The frequency of the signal or current output by a device or circuit, which can vary based on the input or system design.

Stator Poles

Components of an electric machine, such as a motor or generator, that are stationary and create a magnetic field which interacts with the rotor to induce motion or generate electricity.

Rotor Rotation Speed

The speed at which the rotor of a mechanical device, such as an electric generator or motor, spins.
