Question { CPCL, 10852 }

what is the principle of dc generators?


Answer

generators convert mechanical energy to electrical energy

It is based on the principle of production of dynamically
(or motionally) induced e.m.f (Electromotive Force).
Whenever a conductor cuts magnetic flux, dynamically induced
e.m.f. is produced in it according to Faraday's Laws of
Electromagnetic Induction. This e.m.f. causes a current to
flow if the conductor circuit is closed.
