In 1831 Michael Faraday showed that an electromotive force is produced when a wire is moved through the lines of force of a magnet. If the wire is part of a complete circuit, a current flows. In the following years, several inventors made magneto-electric generators ( magnetos ) in which coils of wire were rotated close to the poles of a fixed magnet, or a... 

Michael Faraday is best known for work in the 1820s and 1830s establishing that a moving magnetic field induces an electric potential. He built the first dynamo for electricity generation. He also discovered benzene, invented oxidation numbers, and popularized the terms electrode, anode, and cathode. The SI unit of electrical capacitance is named in his honor. 

Michael Faraday, an English physicist, believed that if electricity could produce magnetism then magnetism could produce electricity. He then showed that a moving magnet could produce an electrical current in a coil of wire. This is the basis of electric generators and transformers. He developed the concept of lines of force. 

Electricity generation as we know it today began when Michael Faraday conducted the famous ring experiment in 1831. This experiment, together with many other experiments of the time, made it possible for Lord Kelvin and Sebastian de Ferranti to patent in 1882 the designs for an electrical machine called the Ferranti-Thompson dynamo, which enabled the generation of electricity on a commercial scale.

Faraday s constant is named for Michael Faraday, 1791-1867, a great English physicist and chemist who discovered the laws of electrolysis, who was the first to isolate metallic sodium and potassium, and who invented the first electric generator. 

The electrical age was built on the discovery in the early 1830s, independently by Joseph Henry (1797-1878) in America and Michael Faraday (1791-1867) in England, of electromagnetic induction, which led directly to the invention of the dynamo to generate electricity from steam-powered rotation. It came to fruition on New Year s Eve, 1879, when Thomas Edison (1847-1931) in rural New Jersey, after systematic and exhaustive experiments, made the first successful incandescent lamp, employing a carbonised filament made from some thread taken from Mrs. Edison s sewing cabinet. The lamp burned undimmed for 40 h, watched anxiously by Edison and some of his numerous collaborators. This lamp was ideal for...

An electrochemical power source comprises two electrodes of different materials immersed in electrolyte, whereby electrode systems with different potentials are formed at the two electrodes. Electrochemical reactions proceed at the two interfaces which involve transfer of electrons between the electrode surface and ions from the solution. The difference between the potentials of the two electrodes generates the electromotive force of the electrochemical power source. When the two electrodes (anode and cathode) are connected to a conductor with a load, electric current which can do work flows between them, i.e., the chemical energy can be converted into an electrical one. Electric current flows due to changes of the valences of the materials at the two electrodes. Michael Faraday established that, when one gram equivalent of any substance takes part in an electrochemical reaction, the quantity of electricity that flows is always equal to 96,487 coulombs (C). This value is called Faraday constant, after the name of M. Faraday, and is denoted by the symbol F. The value of the constant is generally rounded to 96,5(X) C. 

Michael Faraday lecturing at the Royal Institution before Prince Albert and others (1855). The faraday was named in honor of Michael Faraday (1791-1867), an Englishman who may have been the greatest experimental scientist of the nineteenth century. Among his many achievements were the invention of the electric motor and generator and the development of the principles of electrolysis.
