The Innovation and Use of the Electrical Wire - 916 Words

Electrical Wire When metal is formed into a single, flexible strand, or fiber, it is called wire. Metal wire has been used by humans in jewelry and other decorative items since the beginning of the use of metal in the second millennium B.C. This type of use primarily involved precious metals like gold and silver; but also more common metals like copper. But with the discovery of electromagnetism, metal wire was found to be a good conductor of electricity, especially that made of copper. As with most electrical devices, the current form of electrical wire was invented by the Father of Electricity, Thomas Edison. He was awarded a patent in 1892 for what he described as an electric conductor, but was really an insulated wire that was both water and fire proof. Edisons invention consisted of a conducting wire, a covering made of cotton braid, and an outer covering made of non-conducting rubber. (Dini 2006) This new invention could conduct electricity without the danger of starting fires or being shorte d out by water. Wire is produced by forming a part of the metal into a small piece so it will fit through a die that has a hole through which the metal will be drawn. It is then slowly drawn it through a series of smaller and small dies until the diameter of the wire reaches the desired size. It can then be used in everything from wire netting and wire rope to electrical wire; which conducts the nations power. Wire, as an electrical conductor, was invented by ThomasShow MoreRelatedThe Development of Wireless Communication Leading to the Alexanderson Alternator Not much has1200 Words   |  5 Pagesrelaying of information became. The first big innovation in long distance information transfer came through the use of the Telegraph. The Telegraph was a device that transmitted electrical pulses along a wire. This allowed a person at one end of the wire to transfer an electrical signal from one location to another. By varying the pulse of the electrical signal, the first rudimentary messages were sent by Samuel Soemmering in 1809. â€Å"He used 35 wires with gold electrodes in water and at the receivingRead MoreWhat Makes A Motor Work?

But more importantly, how does a motor work and how does it energize things the way it does? Why is the motor still being used as opposed to some newer technological innovation that could potentially be more efficient? There are two distinctions that are subtle but nonetheless important, and that is the difference between and electric motor and an engine. The first(most glaringly at that) obvious difference is that anRead MoreWhat is Wireless Power?697 Words   |  3 PagesHowever, Is it feasible or a stuff of science fiction? Wireless power is the concept of transferring electrical energy from one point to another without wires. In the early 20 century, after Maxwells’ Hertz experiments on electromagnetic waves and before the wire grid, ‘Nikola Tesla devoted much effort toward schemes to transport power wirelessly’ (Kurs, 2007). His approach to wireless power use electromagnetic field of some frequencies using his magnifying coil, he ‘ transmitted electricity wirelessRead MoreFiber Optic Network For Overall Broadband Systems Essay1422 Words   |  6 Pagescorrespondence frameworks including their key innovations, furthermore talks about their innovative pattern towards the following generation.

Although ATT brought in fiber optic technology in 1979, they weren’t the first company to think of such a creative idea. The conception of interchanging data by making use of light was the idea of by Alexander Graham Bell in 1800s. Bell always thought of the prospective that pulses of light can transfer voice signals, but on no account Bell had a reliable light source to experiment on the idea (Cheo, P. 1990).
