alleryThe coil of an AC generator connects to the outside circuit through:
ASprings and gears
BBelts and pulleys
CFuses and switches
DSlip rings and brushes
Answer & Solution
Correct answer: D. Slip rings and brushes
1. The coil keeps rotating, so fixed wires cannot be soldered on.
2. Rings turn with the coil and brushes rub on them.
3. Slip rings and brushes carry the current out.
