Toppr: Better learning for better results - List of Best Conductor of Electricity | Gold, Copper, Steel
Gold is said to be one of the best conductor of electricity. Unlike other metals, gold does not tarnish easily when we expose it to air. On the other hands, other metals like steel or copper corrode when they are in contact with oxygen for a long time. Moreover, it also stays conductive for a longer period. However, gold is quite expensive.
