If you have two independent circuits, and then connect them at two points that are at arbitrary voltages by a single conductor, what happens to the system? A moment after the connection happens, I would assume there to be no current between the circuits since the two circuits would try and establish equal potential at the two points they're connected by, right? But would that actually happen? If you had a current I1 going through one of the circuits for example, and then connected the two circuits together by this one conductor, would I1 change at that instant (unless the two points the conductor is connected to is at equal potential)?
