how is the ac current produced in the alternator changed to dc current?
by diodes inside the alternator
alternating brushes
slip ring rotation
mechanical switches

Explanation:

Diodes are used in alternators to convert AC (alternating current) to DC (direct current). Diodes allow current to flow in only one direction, which is the principle behind rectification (converting AC to DC). Alternating brushes, slip - ring rotation, and mechanical switches are not the components responsible for this AC - to - DC conversion in an alternator.

Answer:

By diodes inside the alternator
