The problem with your position is that this is only true if the copper
and silver conductors are sealed against contact with the air. Both
of these metals are very prone to the development of a film of corrosion
that drastically reduces their conductivity. Gold is very resistant to
corrosion and will quickly have a better conductivity than either
silver or copper when they are all exposed to the air.

I have seen this based on actual experience and not by just quoting
some numbers out of a text book without being able to understand
how to use these numbers.

Care to try again?
