    A battery consists of a variable number 'n' of identical cells having internal resistances connected in series. The terminals of battery are short circuited and the current i is measured. Which of the graph below shows the relation ship between i and n

    A)                        

    B)           

    C)                        

    D)           

    Correct Answer: D

    Solution :

               Short circuited current \[i=\frac{nE}{nr}=\frac{E}{r}\] i.e. i doesn't depend upon n.
