Question

State the principal of an electric motor and write the role of split rings init .Write the energy transformations that takes place when an electric motor works

Answer 1

Principal - force acting on an conductor when the current passes through the conductor when the conductor is placed between the magnetic field

Role of split rings - split rings are used to change the direction of current.

Energy transformations- the energy transformed from mechanical energy to electrical energy when the electric motor works

Answer 2

Answer:

The split ring in the electric motor also known as a commutator reverses the direction of current flowing through the coil after every half rotation of the coil. Due to this the coil continues to rotate in the same direction.
