Ok, this may be a very stupid question but I just can't find a right explanation.
I was reading about how a battery works (i.e. car or AA battery etc) and I found several videos giving the following explanation. (e-) are concentrated on one pole and a positively charged material is in the other pole with an insulation in between. Plug a light bulb and (e-) will rush from one pole to the other passing trough the spring, heating it up, photos are released etc etc, you get light! perfect. The explanation works here.
However, most electronics connect this batteries in series, and in this case, the basic explanation above doesn't make sense. If I have 3 batteries in series (A, B and C) in a device something like this:
device} [-/A/+] [-/B/+] [-/C/+] → {device
I can see how electrons go from C to A passing trough the device powering it. but how about electrons from A and B, how do they reach the device if there is an insulation.
Also according to this explanation, if put + of one battery next to - of another battery, it would drain one battery and leave the other with 2 negatively charged poles separated by the insulation in the middle. I know this is not the case, so I asume that explanation is a simplification of an obviously different process. Anyone could enlighten me?
