electrical wireComprehensive Analysis
Electricity (from Greek ήλεκτρον (electron) "amber") is a general term for the variety of phenomena resulting from the presence and flow of electric charge. Together with magnetism, it constitutes the fundamental interaction known as electromagnetism. It includes many well-known physical phenomena such as lightning, electric fields and electric currents, and is put to use in industrial applications such as electronics and electric..." 2) "Wire" -- As to electrical wire1wirePronunciation: 'wI(-&)r Function: noun Usage: often attributive Etymology: Middle English, from Old English wIr; akin to Old High German wiara fine gold work, Latin viEre to plait, and probably to Greek iris rainbow 1 a : metal in the form of a usually very flexible thread or slender rod b : a thread or rod of such material 2 a : WIREWORK b : the meshwork of parallel or woven wire on which the wet web of paper forms 3 : something (as a thin plant stem) that is wirelike 4 plural a : a system of wires used to operate the puppets in a puppet show b : hidden influences controlling the action of a person or organization 5 a : a line of wire for conducting electric current -- compare CORD 3b b : a telephone or telegraph wire or system; especially : WIRE SERVICE c : TELEGRAM, CABLEGRAM 6 : fencing or a fence of usually barbed wire 7 a : the finish line of a race b : the final decisive moment (as of a contest) <the negotiations came down to the wire> 8 : WIREHAIR - wirelike /-"lIk/ adjective - under the wire 1 : at the finish line 2 : at the last moment - wire to wire or from wire to wire : from start to finish <led the race wire to wire> Pronunciation Symbols A wire is a single, usually cylindrical, elongated strand of drawn metal. Wires are used to bear mechanical loads and to carry electricity and telecommunications signals. Standard sizes are determined by various wire gauges. The term wire is also used more loosely to refer to a bundle of such strands, as in 'multistranded wire', which is more correctly termed a cable. Wire has many uses. It forms the raw material of many important manufacturers, such as the wire-net industry, wire-cloth making and wire-rope spinning, in which it occupies a place analogous to a textile fibre. Wire-cloth of all degrees of strength and fineness of mesh is used for sifting and screening machinery, for draining paper pulp, for window screens, and for many other purposes. Vast quantities of aluminium, copper, nickel and steel wire are employed for telephone and data wires and cables, and as conductors in electric power transmission, and heating. It is in no less demand for fencing, and much is consumed in the construction of suspension bridges, and cages, etc. In the manufacture of stringed musical instruments and scientific instruments wire is again largely used. Among its other sources of consumption it is sufficient to mention pin and hair-pin making, the needle and fish-hook industries, nail, peg and rivet making, and carding machinery; indeed there are few industries into which it does not enter. Not all metals and metallic alloys possess the physical properties necessary to make useful wire. The metals must in the first place be ductile and strong in tension, the quality on which the utility of wire principally depends. The metals suitable for wire, possessing almost equal ductility, are platinum, silver, iron, copper, aluminium and gold; and it is only from these and certain of their alloys with other metals, principally brass and bronze, that wire is prepared. By careful treatment extremely thin wire can be produced. Special purpose wire is however made from other metals (e.g. tungsten wire for light bulb and vacuum tube filaments, because of its high melting temperature).
