Question

hey guys please tell the working principle of electric generator.

Answer 1

Hello Mate,

An electric generator works on the principle of Faraday’s law of electromagnetic induction.

Faraday’s law of electromagnetic induction states that “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
The basic principle of a generator is to convert motion into electricity. Providing this motion requires that either a magnetic field is generated and a wire coil is rotated within it, or a magnetic field is rotated within a stationary coil. The turning of a coil in a magnetic field produces motional emfs in both sides of the coil which add. Since the component of the velocity perpendicular to the magnetic field changes sinusoidally with the rotation, the generated voltage is sinusoidal 


Hope this helps you

Answer 2

When a conductor moves in a magnetic field , an emf is induced across the conductor. This is the only basis on which each and every rotating
electric generator works. Let us discuss the matter in a little bit details so that we can easily understand how does an electrical generator actually work. According to Faraday's law of electromagnetic induction , when a conductor links with a changing flux , it will have an induced emf across it. The value of induced emf across the conductor depends on the rate of change of flux linkage with the conductor. The direction of the induced emf in the conductor can be determined by Fleming's Right Hand Rule . This rule says that on your right hand if you stretch your thumb, first finger and second finger perpendicular to each other, and if you align your right-hand thumb along the direction of motion of the conductor in the magnetic field , and first finger along the direction of magnetic field, then you second finger indicates the direction of emf in the conductor.
