Question 58Electricity & Electronics - Assistant Engineer

The correct answer is B) exciter. An exciter is a small DC generator that is used to supply direct current to the field winding of an AC generator. This DC current from the exciter provides the necessary magnetizing current to the AC generator field, which in turn produces the magnetic field required for the AC generator to produce alternating current. The other options are incorrect because: A) armature refers to the rotating part of a generator that produces the electrical output, C) stator refers to the stationary part of a generator that contains the field windings, and D) rotor refers to the rotating part of a generator that contains the armature windings.
