Question 515Electricity & Electronics - QMED

The correct answer is A) exciter. The generator that is used to supply direct current to the field of an AC generator is commonly known as an exciter. The exciter provides the necessary magnetizing current to the field winding of the main AC generator, which then induces the alternating current in the stator windings. This arrangement allows the AC generator to generate the desired voltage and frequency. The other options are incorrect because: B) rotor - The rotor is the rotating part of the generator that contains the field windings. C) stator - The stator is the stationary part of the generator that contains the armature windings. D) armature - The armature is the part of the generator that produces the output voltage.
