Allows the slip rings to rotate while maintaining contact with the external circuit. Or Transfer/conduct current to the external circuit. Or The connection between the external circuit and coil/slip rings/internal circuit. Tip: component Y shows carbon brushes which are made from graphite. These brushes allow the slip rings to rotate while maintaining electrical contact with the external circuit, alternatively, they transfer current to the external circuit. |

According to the principle of electromagnetic induction an emf/current is induced as a result of the change in the magnetic flux linkage with the coil. Or When the coil rotates there is a change of magnetic flux linked/associated with the coil. According to the principle of electromagnetic induction, an emf/current is induced in the coil. Or There is relative motion between the conductor and the magnetic field. |
