Quizplus · Accepted Answer

The resistivity of a material is given by the equation:$$ho = \frac{m}{ne^2	au}$$where:* $ho$ is the resistivity* $m$ is the mass of the free electrons* $n$ is the free electron density* $e$ is the charge of an electron* $	au$ is the electron mean free pathTherefore, the resistivity of a material depends on all of the following quantities associated with the wire: the free electron density, the free electron mass, and the electron mean free path.
