Confusion about why voltage of a cell decreases as it's used up and how it relates to current
This means decrease of voltage (why?).
According to the graph as voltage decreases, current increases. … The only way I can explain it using the equation V=e-rI is that for some reason internal resistance r increases and as eloctromotive force stays the same, this means decrease in voltage V so both sides …
