Oct 14, 2017 at 1:34 comment added wbeaty The battery diagram is wrong. It doesn't show the current through the center of the battery. If there is one ampere in the wire, then there is one ampere through the electrolyte. Electric circuits are closed loops. (A battery is a charge-pump, and the path for current is through the battery and back out again, same as with any component.)
