Who invented the alternating current generator?
The operating principle of electromagnetic generators was discovered in the years of 1831–1832 by Michael Faraday. The principle later called Faraday's law, is that an electromotive force is generated in an electrical conductor which encircles a varying magnetic flux.
- AC GENERATOR. Principle : A.C. generators or alternators (as they are usually called) operate on the same fundamental principles of electromagnetic induction as D.C. generators. Alternating voltage may be generated by rotating a coil in the magnetic field or by rotating a magnetic field within a stationary coil.
- Electricity is most often generated at a power station by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.
- A dc generator is an electrical machine which converts mechanical energy into direct current electricity. This energy conversion is based on the principle of production of dynamically induced emf. This article outlines basic construction and working of a DC generator.
Italian physicist Alessandro Volta discovered that particular chemical reactions could produce electricity, and in 1800 he constructed the voltaic pile (an early electric battery) that produced a steady electric current, and so he was the first person to create a steady flow of electrical charge.
- These sources are called prime movers, and include diesel, petrol and natural gas engines. Coal, oil, natural gas, biomass and nuclear energy are energy sources that are used to heat water to produce super-heated steam. Non-mechanical prime movers include water, steam, wind, wave motion and tidal current.
- Throughout the next hundred years, many inventors and scientists tried to find a way to use electrical power to make light. In 1879, the American inventor Thomas Edison was finally able to produce a reliable, long-lasting electric light bulb in his laboratory.
- Atoms are made up of even smaller elements, called protons, electrons and neutrons. When electrical and magnetic forces move electrons from one atom to another, an electrical current is formed.
Description. This is Michael Faraday's generator. This apparatus consists of a tube of neutral material wound with a coil of wire, insulated in cotton, and a bar magnet. Ten years after Faraday created the electric motor he returned to his electrical research and discovered electro-magnetic induction in August 1831.

- Michael Faraday was one of the most prolific scientists of the 19th century. A British physicist and chemist, Faraday is best known for his discoveries of electromagnetic induction and the laws of electrolysis. His biggest breakthrough, however, came with his invention of the electric motor.
- Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. The other three fundamental interactions are the strong interaction, the weak interaction and gravitation.
