What is the principal of electric generator?
Answers
The electric generator is a machine for producing electric current or electricity. The electric generator convert mechanical energy into electrical energy.
Principle of working of an electric generator:
Electric generator is an application of electromagnetic induction.
Electric generator works on the principle that when a straight conductor is moved in a magnetic field, then current is induced in the conductor
In an electric generator a rectangular coil is made to rotate rapidly in the magnetic field between the poles of a horseshoe type magnet. When the coil rotates it cut the magnetic field lines due to which current is produced in the coil .
Electric generators are of two types:
Alternating current generator(A.C generator)
A.C. generators or alternators (as they are usually called) operate on the same fundamental principles of as .
Alternating voltage may be generated by rotating a coil in the magnetic field or by rotating a magnetic field within a stationary coil. The value of the voltage generated depends on-
the number of turns in the coil.
strength of the field.
the speed at which the coil or magnetic field rotates
An electric generator works on a principle of Faradays law of electro magnetic induction
