What is an electric generator?
The electrical generator is a device that produces electricity from mechanical energy, usually through electromagnetic induction. The electromagnetic induction acts forcibly by moving the wire loop (rotor) around the stationary lane (stator), which provides an electric field, either through a permanent magnet or electromagnet. According to Faraday's law, this causes a rotor current that can be used to power machines or charging batteries. Possible sources of mechanical energy include steam engines, water falling over a turbine or water wheel, an internal combustion engine, a hand handle, wind turbine, compressed air, solar energy and many more. The electric generator is the basis of our modern electric society. If electrical generators stop working, as would most economies.
The electrical generator was first invented by the Hungarian inventor and engineer Anyos Jedlik sometime between 1827 and 1830. The poison invented a generator, a simple dynamo, at least six years overD Warner von Siemens in Germany and Charles Wheatstone in Britain, whose names are usually associated with the invention of the device. Although the electric generator was invented around 1830, it would not be until Nikola Tesla was pioneering on rotating magnetic fields around 1882 that generators would become suitable for industrial use. The Electrification of the United States occurred in the 90s of the 20th century, helping to cause the second industrial revolution with which electricity is strongly associated.
Today there are electric generators of all imaginable sizes, from 3-6 watts generators to power of light wheels to hydroelectric generators in the Three Gorges dam in China, which will provide 22.5 gigawatts when fully installed in 2012.The (fossil fuels), 16% via Hydro renewable sources such as wind or SLUnion energy. For the environment and health, global efforts to expand electrical production from water, nuclear and renewable sources and contracting electrical production from sources of fossil fuels are underway.
