Answer»

1.Anelectric generatorworks on theprincipleof Faraday's law of electromagnetic induction. Faraday's law of electromagnetic inductionstatesthat “whenever a current carrying conductor are placed in the magnetic field, then a flux is induces in the circuit due to which a current start to flow in the rotor also.

2.Some sources of direct current are cell,batteryand DC generator, etc.
