Features of a Rotating-Coil Generator
To make sure that the rotating coil is always connected to a circuit, without creating a tangle of wires, we use:
Slip rings
- The slip rings rotate with the coil.
Brushes
- The brushes stay in a fixed position and are always in contact with the slip rings.
Results
- Together, slip rings and brushes provide a simple way to deliver an alternating current (AC) to the external circuit.
- This setup ensures the coil can rotate freely without twisting or tangling the connecting wires.
