Mobility of electrons in a semiconductor is defined as the ratio of their drift velocity to the applied electric field. If, for an n - type semiconductor, the density of electrons is \[{{10}^{9}}{{m}^{-3}}\] and their mobility is \[1.6{{m}^{2}}/(V.s)\] then the resistivity \[\left( in\,\,\Omega \,\,m \right)\] of the semiconductor (since it is an n - type semiconductor contribution of holes is ignored) is
