1. The problem statement, all variables and given/known data When you put batteries you place the negative terminals to the positive which supposedly "bumps' each electron to the next battery. However, the positive terminal is positive enough to neutralize the negative terminal and vice versa. Therefore, when I place batteries in series, only the terminals connected to the load are supplying energy. The other terminals should just be neutralizing one another, yes? Even if the electrons are bumped along, how does it accumulate more voltage as it travels through the batteries? 2. Relevant equations Please don't give me overly complicated equations. I'm only in grade 9. 3. The attempt at a solution The only possibility I can think of is that the negative terminal has a greater charge than the positive terminal of the battery. In that case you would have electrons being "bumped along" but the number of "bumped" electrons would be (electrons in negative terminal)-(unneutralized protons in positive terminal), which wouldn't be very efficient.
