Detailed Solution

The function of brushes connected to split rings of the motor is to provide current to the coil.
Brushes are joined to split rings to supply the electric current to the coil. It conducts electricity between stationary wires and moving parts, most commonly in a rotating shaft. In addition, the split ring helps reverse the current direction in the circuit.
