Hi, Sorry if this sounds blatantly obvious but I just wanted to clarify how a battery works. From my understanding, there are electrochemical reactions occurring within a battery that creates electrons on one end of the battery and thus a negative end. Subsequently, the other end is positive. My first question is, due to this charge differential, why can't the electrons just flow from the negative end to the positive end within the battery (I'm going to assume it can't simply because that would defeat the purpose of putting electrons on one end in the first place)? Now, if we connect a conducting wire to the two ends of the battery, what is actually going on - is the voltage created by the ends of the battery causing the conducting electrons of the wire to move to the positive end (towards a lower electrical potential energy)? Or is it that the electrons already on the negative end of the battery are traveling towards to the positive end through the wire? If it's the latter, are the electrons pushing each other one by one? Why can't an insulating wire work then if the source of electrons is from the negative end? Thanks a bunch!
