[Amps] Silver plating

[Steve Thompson]

 From many years ago I recall an article in 'RF Design' where 
someone suggested that oxidation on copper (and other conductors) 
makes less difference than might be expected because the higher 
resistance in the oxide causes the current to flow deeper where 
the conductivity is higher.
