Why is gold used in electronic products as a conductor instead of
silver? I believe silver is the better conductor of the two metals,
but sometimes they seem to use gold instead of silver. Could this be
because the electricity passes on the surface of the metal and
silver's surface is more easily tarnished than that of gold which
doesn't tarnish? (The tarnished silver surface doesn't conduct as well
as gold.)
