Hi. I'm trying to understand a couple of things. When you put a piece of metal on, say the cathode of a battery, I suppose there is a charge transfer from the battery to the metal because the electrons on the cathode have a high potential energy? And so if I connect a piece of metal to both the cathode and another one to the anode, one piece should recieve electrons and the other one should lose electrons. But I cannot make this fit with the capacitance formula Q=CV, because if the two metal pieces are infinitely far apart, C=0 and then no charge is induced at all.
