in case i was wrong(in your point of view) , let me explain my point:
if you notice,the battery have 2 sides,+,-.
every single side works as a large charge.
since the battery (the - side)affect the electrons in the conductor,electrons would move to the + side.
so it can be calculated by colomb law(when q=electron charge,Q=the ion charge)or with the first f(when q=the electron charge).
and if you notice,the more cells(cathods and anods)we use,the higher voltage we get,so if we use 3 anods(+ charges),we will get 1.5*3=4.5 volts.
there is no attraction force between the +,- sides of the battery, bcoz it is covered by some sort of(maybe amoniom cloried)which is not a conductor,and even if there was attraction force,it would be uniform(straight lines of attrachion)......
well,thats it!!
hope i made my self clear
thx for the help..................again
