Actually, gold is a worse conductor than both copper and silver, and only a little better than aluminum.
> and does not corrode in air
This is the real reason for plating contacts in gold. But gold wires would be a bad idea, since they would be worse than both copper and silver wires.
- Gud 2y agoParent didn’t say gold was a better conductor than silver or copper though. How does gold compare to copper- or silver oxide? Which was the point parent was making.
- teddyh 2y agoThe text was unclear; perhaps they did not believe that gold is a superior conductor to copper and silver. But in my experience, many people do think that, and I thought it would be useful to point out that this is not true.
- bluGill 2y agoParent did say gold was a good conductor which is arguable false.
- ssl-3 2y agoAluminum is also an excellent conductor.
- SoftTalker 2y agoBut also corrodes more than copper, making it unsuitable for household wiring unless special precautions are taken.
- ssl-3 2y agoIndeed. It has some practical issues that need properly mitigated, but it is still a very good conductor.
