Question

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

Answer 1

1)When a coil which is carrying current is placed between two magnets it experiences a force.

2)The role of the split rings is to hold and complete the circuit.

3)Electric to mechanical energy

Answer 2

Answer:

when a current carrying conductor is placed between a magnetic feild it experiences a equal and opposite force which helps motor to move

split ring help to reverse the direction of current

it changes electrical energy into mechanical energy
