INTRODUCTION OF DC GENERATOR

An electrical generator is a rotating machine which converts mechanical energy in to electrical energy. This energy conversion is based on the principle of electromagnetic induction.


According to faraday's laws of electromagnetic induction, whenever a conductor is moved in a magnetic field, dynamically induced emf is produced in the conductor when an external load is connected to the conductor the induced emf causes a current to flow in the load.
