Question

Varying the alternator __________________________________, controls its voltage output?

Option 1: Color
Option 2: Temperature
Option 3: Voltage regulator
Option 4: Size

Answer 1

The voltage output of an alternator is controlled by a voltage regulator.

Step-by-step explanation:

The voltage output of an alternator can be controlled by varying the voltage regulator. The voltage regulator is a component that regulates the voltage level by adjusting the current flow in the field winding of the alternator. By increasing or decreasing the current flow in the field winding, the voltage output of the alternator can be varied.
