Discuss effect of impurity, temperature and alloying on the electricity conductivity of metal.
For an ideal crystal with no impurities and imperfections mean free path at 0 K is infinite. Which is, there are no collisions and electrical conductivity is ideally infinite. Introduction of solute atoms into the crystal results in collisions, decreasing mean free path and the conductivity. At temperatures above 0 K the atoms vibrate randomly about their mean positions. These vibrations, destroys initial periodicity of a crystal and interferes with electron motion. Thus, free mean path and conductivity decreases, with increasing temperature. Pure metal has less electrical resistivity than alloys. Alloys have a higher electrical resistivity. As resistivity increases the conductivity decreases.
