The invention of the generator
In 1831 AD, Faraday passed a wire in a closed circuit through an electromagnetic field. When the wire rotated, current flowed through the wire. Faraday therefore understood that there is a certain close relationship between electricity and magnetic field, and discovered electromagnetic induction principle. This principle that plays an important role in the development of human society says: "When the magnetic force lines of the magnetic field change, a current will be induced in the wires around it."
Faraday is convinced that using this principle can definitely Create a generator that actually generates electricity.
Principle of generator
A generator is a device that converts mechanical energy into electrical energy. The energy contained in various primary energy sources is first converted into mechanical energy through the prime mover, and then converted into electrical energy through the generator, and then sent to various power consumption situations through the power transmission and distribution network.
Due to different forms of primary energy, different generators can be made.
Using water conservancy resources and hydraulic turbine , a hydraulic generator can be made; due to different reservoir capacities and water head heights, hydraulic generators with different capacities and speeds can be made.
uses coal, oil and other resources, and cooperates with boilers and gas turbines to make turbine generators . Most of these generators are high-speed motors.
In addition, there are various types of generators that use wind energy, atomic energy , geothermal and other energy.
The use of electricity has enabled mankind to truly enter the era of civilization.
