Question

Differentiate between electric motor and electric generator

Answer 1

A electric motor is used to produce rotational motion from an electrical supply. In a motor an electric current is passed through the coil. The coil then creates a magnetic field that interacts with the already existing magnetic field .This interaction forces the coil to rotate .
The generator is used to produce an electric current from rotational motion . In a generator the rotation causes the coil to rotate inside the magnetic field. This induces an alternating current in the coil.
For a motor the input energy is electrical energy and useful output is mechanical energy.
For a generator the input energy is mechanical energy and the useful output energy is electrical energy.

Answer 2

The main difference between the two is that the Motor is an electric device which converts electrical energy into mechanical energy. The generator is vice versa of that motor. It converts mechanical energy into electrical energy.
