    The dimensions of thermal resistance are

    A)            \[{{M}^{-1}}{{L}^{-2}}{{T}^{3}}K\]                                   

    B)            \[M{{L}^{2}}{{T}^{-2}}{{K}^{-1}}\]

    C)            \[M{{L}^{2}}{{T}^{-3}}K\]

    D)            \[M{{L}^{2}}{{T}^{-2}}{{K}^{-2}}\]

    Correct Answer: A

    Solution :

                       Thermal resistance            \[=\frac{l}{KA}=\left[ \frac{L}{ML{{T}^{-3}}{{K}^{-1}}\times {{L}^{2}}} \right]=[{{M}^{-1}}{{L}^{-2}}{{T}^{3}}K]\]
