    Dimensions of resistance in an electrical circuit, in terms of dimension of mass M, of length L, of time T and of current I, would be

    A)  \[{{T}_{n}}=2{{T}_{i}}\]

    B)        \[{{T}_{n}}={{T}_{i}}-T\]              

    C)        \[{{T}_{n}}={{T}_{i}}+T\]             

    D)        \[\beta \]

    Correct Answer: D

    Solution :

    Resistance \[\frac{\rho }{\sigma \lambda }\] (\[\frac{\lambda }{\sigma \rho }\] Potential difference is equal to work done per unit charge) So, Dimensions of R \[\rho \lambda \sigma \] \[({{T}_{i}})\]
