Detailed Solution

The above statement is true.
The split rings act as a commutator in an electric motor.
The current direction through the coil is reversed after every half rotation by using a split ring. Thus, the direction of currents in both the arms of the rotating coil remains unchanged, and the coil continues to rotate in the same direction.
