Physics - Current Electricity Question with Solution | TestHub

Mobility of electrons in a semiconductor is defined as the ratio of their drift velocity to the applied electric field. If, for an $\text{N}$-type semiconductor, the density of electrons is $10^{19}{m}^{-3}$ and their mobility is $1.6m^2{\text{V}}^{-1}{\text{s}}^{-1}$, then the resistivity of the semiconductor (since it is an $\text{N}$-type semiconductor contribution of holes is ignored) is close to:
