ahemm.. hehehe
the wire would still be the same, its still copper | silver | gold.
ang electron from an energy source will flow to the copper1, then the extra electron from copper1 to copper2.. and so on and so forth until maabot sa load side sa circuit which will then be used up ang energy either as heat | mechanical (fans). so in this example, you will notice nga gipasa lang ang electrons without changing the copper to another element or unsa ba.
and how many electrons, based on ampere defined in wiki;
"Around 6.242 × 10e18 electrons passing a given point each second constitutes one ampere."
kana lang.. sakto bani?..
