Question

If silver is the best conductor of electricity, why is gold used in electronics instead?

In: Engineering

Answer 1

If conductivity matters then copper is the most cost efficient solution. The difference to silver is marginal, so a silver wire can be like 2% thinner for the same resitivity, at a high multiple of the cost.

Gold is used for exposed contacts that shouldn’t corrode
