Q. Which is the better silver wire or copper wire?

Answer

Gold is the third-most conductive metal after silver and copper. Silver's conductivity is 63 x 106 Siemens/meter, which is about 7% greater than that of annealed copper's 59 x 106 siemens/meter. When comparing 24-gauge, 1000-foot-long silver and copper wire, there is only a little variation in resistance (the amount of electricity lost as a current passes from point A to point B through a material). Copper wire has a somewhat higher resistance, but only by 2 ohms. Conductivity is best in silver, next in copper. Copper is the de facto norm for electrical uses worldwide, despite silver being the most conductive alloy on Earth. Silver wire has a good electrical conductivity than copper wire, however silver wire has downsides that make copper wire the superior alternative in most instances.
