    For a conductor, if temperature applied across it is increased

     

    $m^2 V^{-1} s^{-1}$ is the SI unit of which of the following ?

    Concepts Covered - 1

    Mobility
    1. Mobility-

    $
    \mu=\frac{v_d}{E}
    $

    $\mu-$ Mobility
    $v_d$-Drift velocity
    Relation between conductivity and Mobility:

    $
    \sigma=\mu n e
    $
    Where n is the number of electrons per unit volume, e is the charge of the electron and $\sigma$ is the conductivity.

    In case of a conductor conductivity decrease with the increase of temperature and in the case of semiconductor conductivity increase with increase in temperature.
