    The voltage V and current \[I\] graph for a conductor at two different temperatures \[{{T}_{1}}\]and \[{{T}_{2}}\] and shown in the figure. The relation between \[{{T}_{1}}\] and \[{{T}_{2}}\] is                

    A)  \[{{T}_{1}}>{{T}_{2}}\]                 

    B)  \[{{T}_{1}}<{{T}_{2}}\]

    C)  \[{{T}_{1}}={{T}_{2}}\]                 

    D)  \[{{T}_{1}}=\frac{1}{{{T}_{2}}}\]

    Correct Answer: A

    Solution :

    Resistance = Slope of \[V-I\]graph Resistance \[\propto \]Temperature                                 \[{{R}_{1}}>{{R}_{2}}\] then                      \[{{T}_{1}}>{{T}_{2}}\]
