In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electric current) in one or more directions. Materials made of metal are common electrical conductors. Electric current is generated by the flow of negatively charged electrons, positively charged holes, and … Meer weergeven The resistance of a given conductor depends on the material it is made of, and on its dimensions. For a given material, the resistance is inversely proportional to the cross-sectional area. For example, a thick copper Meer weergeven Conduction materials include metals, electrolytes, superconductors, semiconductors, plasmas and some nonmetallic … Meer weergeven The ampacity of a conductor, that is, the amount of current it can carry, is related to its electrical resistance: a lower-resistance conductor can carry a larger value of current. The resistance, in turn, is determined by the material the conductor is made … Meer weergeven • BBC: Key Stage 2 Bitesize: Electrical Conductors • The discovery of conductors and insulators by Gray, Dufay and Franklin.
