Detailed Solution

The above statement is true.
For the continuous rotation of the coil in the same direction, the current in the coil must be reversed. A split ring is used for reversing the direction of the current in the coil. Therefore, after every half rotation of the coil, the direction of motion of the coil remains the same, and the coil continues its rotation in the same direction. Thus, the function of the split ring is to reverse the direction of current in the coil in an electric motor.
