define principal DC generator |
|
Answer» An electrical Generator is a machine which converts mechanical energy (or power) into electrical energy (or power).Principle : 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. It is based up on the principal of the electromangetic induction, when a coil rotates between the 2 poles of a strong magnet a current is induced in the coil... |
