What is the role of the split-ring in an electric motor?

Text Solution

Verified by Experts

With the help of split-ring commutator, the direction of the current through the coil gets reversed after every half rotation of the coil. Thus, the direction of rotating couple remains unchanged and the coil continues to rotate in the same direction.
