Detailed explanation-1: -Copper is used for electrical wiring because it is a good conductor of electricity.
Detailed explanation-2: -Metals are good conductors (both of heat and electricity) because at least one electron per atom is free: i.e., it is not tied to any particular atom, but is, instead, able to move freely throughout the metal.
Detailed explanation-3: -Metals have a high melting point and are usually a solid at room temperature. They are also ductile. This means that they can be easily stretched. Finally, metals are good conductors of heat and electricity.
Detailed explanation-4: -Silver: The single most conductive metal, silver conducts heat and electricity efficiently thanks to its unique crystal structure and single valence electron.
Detailed explanation-5: -Pure silver is the finest conductor of electricity. Yet unsurprisingly, it is not one of the metals that are used to carry electricity most frequently. There are a few disadvantages to the widespread usage of pure silver. More items
