If you skin the cables of virtually every electronic appliance you have in your home, you’re likely to find copper inside them. Have you bothered to ask why? While almost all metals (the solid ones, specifically) are good conductors of electricity on their own, copper seems to be the most favored. Why is that?
Simply put, copper lords over almost every metal (silver is a better conductor, but its steep price tag is one thing manufacturers won’t dare touch) when it comes to electrical conductivity. Copper wires have been shown capable of carrying more current per diameter of wire, while depleting relatively less electrical charge when current flows through it.
