    Two non-ideal identical batteries are connected in parallel. Consider the following statements                                   [MP PMT 1999]            (i)   The equivalent e.m.f. is smaller than either of the two e.m.f.s            (ii)  The equivalent internal resistance is smaller than either of the two internal resistances

    A)                    Both (i) and (ii) are correct

    B)                    (i) is correct but (ii) is wrong

    C)                    (ii) is correct but (i) is wrong

    D)                    Both (i) and (ii) are wrong

    Correct Answer: C

    Solution :

               Because \[{{E}_{eq}}=E\] and \[{{r}_{eq}}=\frac{r}{2}\]
