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