Because if no, then its potential will be zero, and so there will be a difference in potentials between one of the conductors and the wire, so the charge should still flow into the wire. I''ll try to rephrase the question, because it seems people keep getting my question wrong - in general, I can''t understand why charges should always flow until both of the conductors reach the same …
