    A potentiometer consists of a wire of length 4 m and resistance 10 W. It is connected to cell of emf 2 V. The potential difference per unit length of the wire will be [Pb. PET 2002]

    A)         0.5 V/m

    B)                        10 V/m

    C)         2 V/m                              

    D)         5 V/m

    Correct Answer: A

    Solution :

                                             Potential difference per unit length \[=\frac{V}{L}=\frac{2}{4}=0.5\,V/m\]
