Q. The working of a dynamo is based on the principle of
- electromagnetic induction
- conversion of energy into electricity
- Magnetic effect of current
- heating effect of current
Dynamo - a device that makes direct current electric power using electromagnetism.Dynamo is an electric generator that converts mechanical energy into electrical energy but its output is direct current. This works in the principle of electromagnetic induction under which if a magnet is moved near a coil, electricity is developed in the coil.
