Which of the following components are used to convert alternating current produced in the DC generator armature windings to direct current?

AArmature and equalizer
BRotor and interpoles
CField and exciter
DCommutator and brushes
AI Explanation

The correct answer is D) Commutator and brushes. The commutator and brushes are the components used to convert the alternating current (AC) produced in the DC generator armature windings to direct current (DC). The commutator is a set of copper segments that are connected to the armature windings, and the brushes make contact with the commutator to collect the DC output. The other options are incorrect because they do not directly relate to the conversion of AC to DC in a DC generator. Armature and equalizer are components within the generator, but not specifically involved in the AC to DC conversion. Rotor and interpoles are also generator components, but do not perform the AC to DC conversion. Field and exciter are responsible for generating the magnetic field, but do not convert the AC to DC.
