Question

I want essay on generator

Answer 1

An electric generator is basically an electric motor working backwards. An electric motor converts electrical energy into mechanical energy, and an electric generator converts mechanical energy into electrical energy. An electric generator looks almost identical to an electric motor. Each consists of a loop that is able to rotate in a magnetic field. The electric motor uses electrical energy to make the loops rotate which creates mechanical energy. In the electric generator it uses mechanical energy to make the loops spin resulting in the creation of electric current within the loop.

The way an electric generator functions is based on the principal of "electromagnetic induction". Electro magnetic induction is when you move a wire through a magnetic field causing electric current to enter the wire. As long as the magnet and the coil move relative to each other, a potential difference is produced across the coil and current flows in the coil.
