Draw a labelled diagram of an electric motor. Explain its principle and working. What is the function of a split-ring in an electric motor?

Text Solution

Verified by Experts

Split-ring in an electric motor takes the current from the battery and passes it on the coil through the brushes after reversing its direction after every half revolution. The reversal of current in the coil reverses the direction of forces acting on the sides of the loop.
