Hii
An Electric Generator is a device used to generate electricity by converting mechanical energy into electrical energy to be used in external circuit. It is an essential device used to supply the electrical power at the time of power outage and offers continuity of daily activities or various business operations. The generators are designed with different physical and electrical configurations to be used in different appliances. The reverse conversion, i.e., the conversion of electrical energy to mechanical energy is carried out by an electric motor.
Principle
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
Working
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.

electric generator
An electric generator is an electrical device, which converts mechanical energy into electrical energy. It works on the principle of Faraday’s law of electromagnetic induction.
An electric generator takes mechanical energy from Steam turbine, Water turbine, gas turbine, and prime movers with the help of shaft. After that converts it to the electrical energy with the help of their external circuit.

principle of a generator
The basic principle is referred to as ‘induction.’ You need to research that term.
What you will not learn is that induction is an exchange of virtual photons which are superpositioned at both the source and emitter. They don’t actually travel, albeit, they have mass, unlike a ‘real’ photon, they could not travel at v=c if the wanted to.
Massive things can superposition, it is not a form of ‘travel.’ You need to look up Feynman-Wheeler’s Absorber Theory, then Cramer refined it into the Transactional Hypothesis.

Working of Generators:
Generators are basically coils of electric conductors, normally copper wire, that are tightly wound onto a metal core and are mounted to turn around inside an exhibit of large magnets. An electric conductor moves through a magnetic field, the magnetism will interface with the electrons in the conductor to induce a flow of electrical current inside it.
