The specific resistance of a conductor depends on\

Question

Professor PC Thomas Classes · Answer

Specific resistance or resistivity of a material is a constant for the material at a given temperature.\ $ho=\frac{\mathrm{m}}{\mathrm{ne}^{2} 	au}$, where $ho=$ resistivity, $\mathrm{m}=$ mass of electron, $\mathrm{n}=$ number of free electrons per unit volume, $	au=$ relaxation time ie, the time for which the electrons travel through the material free from collision with atoms.\ m and e are universal constants. n and $	au$ depends on material and temperature. $	herefore ho$ depends on nature of material and temperature.
