# Potential of cells in series

If two cells are connected in series, say,

I understand that charge from cell 1 have a potential of 10 V would increase it's potential by 5V on moving through the second cell (neglecting internal resistance).

But since both are cells, doesn't the 5V cell have the capability to produce charge as well? The charge coming from that cell should only have a potential of 5V

I know this theory is definitely wrong but I want to know why. I think it's because of the way the cells are connected but I'm sure. In any case, even if I'm right, please elaborate.

• Yeah, sorry. My mistake. I'll edit the question. – LeroyJD Aug 2 '16 at 5:27
• That charge that went through only the 5 V cell started at a potential of 10 V. So its final potential is 15 V. (I'm assuming here that 0 V is at the far left of your diagram, and the polarity of the cells is positive to the right. Conventionally, the longer line is the positive side of the cell.) Am I not understanding the question? – garyp Aug 2 '16 at 11:18
