My problem is that there are n cells connected in parallel, connected to an external resistor.
Now can we use Kirchoff's loop rule to evaluate the current through the resistor by considering a loop from the +ve terminal of a single cell to the -ve terminal of that cell?
If we do then wouldn't the equation be
and $i$ will come out to be $E/R$? This implies that the current in resistor $R$ would remain constant even if a cell is removed. But superposition of current says it will be reduced.
