Vedclass · Answer

(B) For $n$ identical cells connected in parallel,each with electromotive force $E$ and internal resistance $r$,the total electromotive force is $E_{eq} = E$ and the equivalent internal resistance is $r_{eq} = \frac{r}{n}$.The total current $I$ flowing through the external resistance $R$ is given by:$I = \frac{E}{R + \frac{r}{n}} = \frac{nE}{nR + r}$.To maximize the current $I$,the denominator $(nR + r)$ must be minimized. If $R Therefore,the condition for maximum current in a parallel combination is $R << r$.

To get the maximum current from a parallel combination of $n$ identical cells,each of internal resistance $r$,connected to an external resistance $R$,which of the following conditions must be satisfied?
