If silver is the best conductor of electricity, why is gold used in electronics instead?
In: Engineering
One of the great things about gold is that chemically it is very stable. Under typical conditions, it’s generally quite happy to just sit there and remain gold and not react with much in its environment.
Silver is not as stable. More specifically, it’s likely to tarnish over time, and as it tarnishes it becomes less useful as a conductor. Silver will tarnish from humidity in the air, which is a pretty tough thing to avoid in many potential use cases.
