    The electromotive force of primary cell is \[2\,\,V\]. When it is short circuited it gives a current of \[4\,\,A\]. Its internal resistance in ohm is

    A)  0.5                                        

    B)  5.0

    C)  2.0                                        

    D)  8.0

    Correct Answer: A

    Solution :

    When cell is short circuited, then total resistance is equal to internal resistance of coil. \[E=ir\] \[r=\frac{E}{i}=\frac{2}{4}=0.5\,\,ohm\]
