Im not asuming a condition of a switch, im interested in a plain
wire, imagine a superconduktor contra a copper wire, no switches,
then what do my questions end up to that?!

Simple physics would sugest it would be possible to
have a large current at femto volt levels, no?

Quantum mechanics have a lot upp its sleve!

I dont imagined that, but what did the manufacturer actually imagine?
