What is Electrical conductor?
{{for|a conductor of music|conducting}} {{no sources|date=April 2021}} [[File:Lautsprecherkabel Makro nah.jpg|thumb|Copper wire as electrical conductor]] A '''conductor''' is a material which allows [[electricity]], [[heat]] or [[sound]] to flow through it. An ''' electrical conductor''' conducts electricity. The ability to conduct electricity is called [[electrical conductivity]]. An excellent electrical conductor has high conductivity and low resistivity. [[Electrical resistivity]] is the reciprocal/opposite of conductivity. Prominent electrical conductors include: * Copper * Aluminum * Gold * Silver * Water * Human skin [[Metal]]s, like [[iron]] and [[copper]], are used to make [[wires]] to carry [[electric current]]. [[Plasma (physics)|Plasma]] is an excellent conductor of electricity and is used for many purposes but metals are more used. [[Impurity|Impure]] [[water]] can also conduct electricity. Living [[tissue]]<nowiki/>s, as in the [[human body]], are wet and therefore conductors of electricity. Some materials are ''[[semiconductor]]s''. This means that electricity ''can'' flow through them to a certain temperature and below that semiconductors <ref>{{Cite web|title=What is a semiconductor? - Types, Advantages, Applications and more|date=25 May 2021|url=https://electricalarea.com/what-is-a-semiconductor/|access-date=2021-09-30|language=en-US|archive-date=2022-12-08|archive-url=https://web.archive.org/web/20221208223625/https://electricalarea.com/what-is-a-semiconductor/|url-status=dead}}</ref>do not pass electricity. Some materials are ''[[resistors]]''. This means electricity does not easily flow through them. A material that stops [[electric current]] is called an [[insulator (electricity)]]. [[Wire]]s are covered with insulators like [[plastic]] to stop the electricity from leaving the wire. Some materials when very cold, are [[superconductor]]s. They offer no resistance at all to the flow of electricity. Most conductors' resistance becomes higher at higher temperatures. ==
