<onlyinclude>'''Wires''' are pieces of metal that transport electricity.</onlyinclude> They are key to all electrical devices, from the [[circuit]] board in a computer to the [[transformer]] in a neighborhood, or even the [[electrical transmission]] system carrying [[electric power]] hundreds of [[kilometer]]s.

==Wire gauge (size)==
Differing cross sectional sizes of wires are known as [[wire gauge]]s, they are organized by the American Wire Gauge system (AWG). Knowing the gauge is important because each is rated for a different [[ampacity]], meaning that each wire size has a maximum [[current]] it can handle before damage (possibly serious) might occur.

==Composition==
[[File:wires.jpg|400px|thumb|Figure 1. An insulated wire containing color coded copper wires.<Ref>Wikimedia Commons [Online], Available: https://commons.wikimedia.org/wiki/File:600V_CV_5.5sqmm.jpg#/media/File:600V_CV_5.5sqmm.jpg</ref>]]
Most wires are coated in an [[electrical insulator|insulating material]] in order to prevent electrocution when handling. Typically this insulating material is composed of plastic or rubber-like material. However, very large wires used for electrical power transmission aren't always insulated since they are far overhead and their danger is limited. Smaller wires are often made of [[ductile]] material so that they can bend and be bent easily.

====Copper====
[[Copper]] wire - the most commonly used conductive wire - is cost effective and offers a low [[resistivity]] (only silver has a lower resistivity but is very expensive). It is used in many commercial applications and therefore is widely available and comes in a variety of different gauges. Copper is quite ductile as well as being a good [[conductor]], which is an added advantage for many applications.

====Aluminum====
Although [[aluminum]] wire is more cost effective than copper, its properties are not as favorable, it has a higher [[resistivity]] and has a lower [[elasticity]] (it's more [[plasticity|plastic]]) meaning that if heated enough it expands and is more susceptible to diverging from its original shape once the [[heat]] is reduced.

'''Solid''' wires have only one conductive strand and are much more difficult to move or bend. They are typically used when a lot of movement isn't necessary<ref name=R1 /> or when the wire is small (see figure 1).

'''Stranded''' wires contain a large number of thin solid wires that are wrapped around each other to make a single larger wire. They are much more flexible than solid wires and are often used when the wire undergoes frequent movement or manipulation<ref name=R1 /> (see figure 1).
