You can use any type of wire from Electrodynamics. However, the better the wire, the more current it can take and the less resistance (loss) it has. For example, a copper wire would work, but it would lose a lot of power along the way. It would also burn if you put too much power through it. On the other hand, if you used a gold wire, it has a much higher limit on current and less resistance. The best is Superconductive wire because it has no resistance and no limit on current.
What cable do we use to connect all of that?
