In a standard galvanic cell, I was wondering why there is not at least a little
current even with an open circuit. Obviously, charges cannot flow from one
electrode to another, but we still have a metal connected to a positive pole.
So, should there not be some movement of charge as electrons in the metal move
toward the positively charged electrode?
