Question:
how is the slip rings and the brushes changing their positions in the ac generator
Answer:
Slip rings and brushes are not used in AC conductors. They are only used in DC conductors. In a DC conductor, the slip rings allow the transfer of alternating e.m.f. induced in the rotating coil to the external circuit. Each ring is connected to one end of the coil wire and is electrically connected to the external circuit via the conductive carbon brushes.
