  • question_answer
    To get the maximum current from a parallel combination of n identical cells each of internal resistance r in an external resistance R, when                                                       [DPMT 1999]

    A)                    \[R>>r\]

    B)                                      \[R<<r\]

    C)                    \[R=r\]                            

    D)            None of these

    Correct Answer: B

    Solution :

               Cells are joined in parallel when internal resistance is higher then a external resistance. (R <<r) \[i=\frac{E}{R+\frac{r}{n}}\]
