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. The flow of negatively charged electrons generates electric current, positively charged holes, and positive or negative ions in ...

Copper is the electrical conductor in many categories of electrical wiring. [ 3 ] [ 4 ] Copper wire is used in power generation , power transmission , power distribution , telecommunications , electronics circuitry, and countless types of electrical equipment . [ 5 ]
[1] [2] [3] For example, if a 1 m 3 solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m. Electrical conductivity (or specific conductance) is the reciprocal of electrical resistivity. It represents a material's ability to conduct ...
Aluminum building wiring is a type of electrical wiring for residential construction or houses that uses aluminum electrical conductors. Aluminum provides a better conductivity-to-weight ratio than copper, and therefore is also used for wiring power grids , including overhead power transmission lines and local power distribution lines , as well ...
Hook-up wire is small-to-medium gauge, solid or stranded, insulated wire, [11] used for making internal connections inside electrical or electronic devices. It is often tin-plated to improve solderability. Wire bonding is the application of microscopic wires for making electrical connections inside semiconductor components and integrated circuits.
Coaxial cable, or coax (pronounced / ˈ k oʊ. æ k s /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.
Electrical devices often use copper conductors because of their properties, including their high electrical conductivity, tensile strength, ductility, creep resistance, corrosion resistance, thermal conductivity, coefficient of thermal expansion, solderability, resistance to electrical overloads, compatibility with electrical insulators, and ...
