Hello! I am confused about this circuit representation. I am not familiar with how it works. I was under the impression charge cannot flow across a capacitor (a wire is required). So how does charge move in the following circuit? Not across the battery - since the charge is supposed to be separated, right? Again, as for a capacitor, a wire is required to provide a path for the electrons (or whatever) to move. There is nowhere for it to flow through. Are the points labeled in and out connected somehow? http://en.wikipedia.org/wiki/File:Cell_membrane_reduced_circuit.svg Thanks in advance.
