Temperature dependence of resistivity p(T) of semiconductors, insulators and metals is significantly based on the following factors:A. Numbr of charge carriers can change with temperature TB. time interval between two successie collisions can depend of TC. length of material can be a function of TD. mass of carriers is a function of T. |
Answer» Correct Answer - A::B The resistivity of a metallic conductor is given by `e=(m)/(m e^(2)tau)` When n is number of charge carriers per unit volume which can change with temperature T and `tau` is time interval between two successive collisions which decreases with the increase of temperature. |
