Which is a better conductor: gold or silver? What’s the best conducting metal?

Google would quickly return the answer to Conductivity and electrical resistivity.

Silver (Ag) is the metal with highest conductivity.

This is a great graph…

Copper Alloy Tips High Electrical Conductivity and Thermal Conductivity

Silver is the most efficient conductor of electricity. However, it has two disadvantages.

Copper (Cu), is often used in situations where oxidation is not a concern, such as in home wiring or in electric motors.

If oxidation is a problem, gold (Au), is almost always used. To overcome corrosion problems, it is common to use gold plating in printed circuit boards and electronic connectors.
