Question

resistivity of Copper and silver

Answer 1

Though silver wire is roughly 7 percent more conductive than a copper wire of the same length, silver is a significantly rarer metal than copper. Combined with silver's tendency to oxidize and lose efficiency as an electrical conductor, the relatively minor increase in conductivity makes copper a more sensible option in most scenarios. Silver wire, however, is generally reserved for more sensitive systems and specialty electronics where high conductivity over a small distance is prioritized.

Answer 2

The conductivity of silver clocks in at 63 x 10^6 siemens/meter, roughly seven percent higher than the conductivity of annealed copper, which stands at 59 x 10^6 siemens/meter. ... The resistance of the copper wire is a mere 2 ohms higher.
