question_answer
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 and their mobility is then the resistivity of the semiconductor (since it is an n-type semiconductor contribution of holes is ignored) is close to: [JEE Main 09-Jan-2019 Morning]
