[[File:Wire3Core.png|right|300px|thumb|[[Wire|Wires]] have [[metal]] inside them because [[metal]] makes a good '''electrical conductor'''.]]An '''electrical conductor''' is a [[material]] that allows [[electricity]] to flow through it easily.

[[Carbon]] in the form of [[graphite]] is an exception to this.: [[Salt]]s that are [[molten]] or [[dissolve]]d in [[water]] are '''electrical conductors'''.: [[Salt]]s make good '''conductors''' when the [[ion]]s are free to move through the [[substance]].: To determine if an [[object]] is a good '''electrical conductor''' the [[object]] can be added to a [[circuit]]. If a [[Electrical Current|current]] flows then it is a good '''conductor'''.: To compare the '''[[Electrical Conductivity|conductivity]]''' of different [[object]]s an [[ammeter]] can be added to the [[circuit]]. The higher the [[Electrical Current|current]] the better the [[object]] is at '''conducting'''. ==Key Stage 4=====Meaning===An '''electrical conductor''' is a [[material]] with a very low [[Electrical Resistance|resistance]] to the flow of [[electricity]]. ===About Electrical Conductors===: [[Metal]] [[element]]s are good '''electrical conductors'''.: [[Metal]]s make good '''conductors''' due to the [[Metallic Bond|metallic bonds]] in which a sea [[Delocalised Electrons|delocalised electrons]] is free to move past a [[lattice]] of [[Positive Ion|positive]] [[metal]] [[ion]]s.: [[Non-metal]] [[element]]s are usually poor '''electrical conductors''' as [[electron]]s are not free to move from one [[atom]] to another. [[Carbon]] in the form of [[graphite]] is an exception to this.: [[Salt]]s that are [[molten]] or [[dissolve]]d in [[water]] are '''electrical conductors'''.: [[Salt]]s make good '''conductors'''when the [[ion]]s are free to move through the [[substance]].: To determine if an [[object]] is a good '''electrical conductor''' the [[object]] can be added to a [[circuit]]. If the [[ratio]] of [[Potential Difference|potential difference]] to [[Electrical Current|current]] is low then it is a good '''conductor'''.: To compare the '''[[Electrical Conductivity|conductivity]]''' of [[Electrical Component|components]] in a [[circuit]] an [[ammeter]] can be added in [[Series Circuit|series]] with the [[Electrical Component|component]] and a [[voltmeter]] in [[Parallel Circuit|parallel]] to the [[Electrical Component|component]]. The smaller the [[Electrical Resistance|resistance]] the better the [[object]] is at '''conducting'''. {| class="wikitable"|-|[[File:ResistanceComponent.png|center|500px]]|-| style="height:20px; width:200px; text-align:center;" |A [[Circuit Diagram|circuit diagram]] showing how to find the [[Electrical Resistance|resistance]] of an unknown [[Electrical Component|component]].|} ===References=======AQA==== :[https://www.amazon.co.uk/gp/product/0008158770/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=0008158770&linkCode=as2&tag=nrjc-21&linkId=ec31595e720e1529e49876c3866fff6e ''Conductor (electrical), page 48, GCSE Physics; Student Book, Collins, AQA '']:[https://www.amazon.co.uk/gp/product/1782945970/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945970&linkCode=as2&tag=nrjc-21&linkId=a120d24dcc7cc7a58192069a3aafc1d2 ''Conductors; electrical, page 99, GCSE Physics; The Complete 9-1 Course for AQA, CGP, AQA ''] ===References=======AQA==== :[https://www.amazon.co.uk/gp/product/1782945970/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945970&linkCode=as2&tag=nrjc-21&linkId=a120d24dcc7cc7a58192069a3aafc1d2 ''Electrical conductors, page 99, GCSE Physics; The Complete 9-1 Course for AQA, CGP, AQA '']
