I was just wondering why it isn't possible for current to flow from the -ve of one battery to the +ve of another? And why when you measure the voltage between the two, you get zero? The -ve of one battery should still be attracted to the +ve of another I would think.
Even if no current can flow between the two due to the chemical reaction process that takes place(though I'm not sure why this reaction still couldn't take place), I would think you could still at least measure the potential difference between the two batteries. I mean voltage is still voltage right? The 0v neg. of battery A should still be attracted to the 9v pos. of battery B.
Obviously I'm wrong about this because I just tried to measure with my multimeter and ended up with 0v between the two 9v batteries (voltage between neg. term. of one and pos. term. of the other), but I can't figure out why.
