Question

what is the function of spit ring commutator and carbon brushes?

please give 3: marks answer

Answer 1

To keep the torque on a DC motor from reversing every time the coil moves through the plane perpendicular to the magnetic field, a split-ring device called a commutator is used to reverse the current at that point. The electrical contacts to the rotating ring are called "brushes" since copper brush contacts were used in early motors. Modern motors normally use spring-loaded carbon contacts, but the historical name for the contacts has persisted.

Answer 2

The funstion of tje split ring ie commutator is to revers the direction of the current and the function  of carbonbrushes is that it acts as a inter mediate connecter between the battery and split rings as when split rings rotate the wire also rotates and hence can disconnect
