Excuse the newby question, but this is bothering me...
Could someone explain to me why two identical batteries when connected in series do not form internally a circuit between the touching positive end of one battery and the touching negative end of the other and proceed to short the ends in contact out?
Obviously this doesn't happen since many electronics use batteries in series all the time, but what is wrong with this explanation? Why is there no potential difference between opposite ends of different batteries touching, but there is a potential (battery is shorted) between opposite ends of the same battery when connected. If the batteries are manufactured identically why should there be a difference between its own negative terminal and someone else's negative terminal?
Thank you!
