The difference in the variation of resistance with temperature in a metal and a semiconductor arises essentially due to thedifferencein the……….

Answer»

crystal STRUCTURE.
VARIATION of the number of charge carriers with temperature.
TYPE of BONDING.
variation of scattering mechanism with temperature.

Solution :variation of the number of charge carriers with temperature.
As the temperature of metal increases, the number of charge carriers does change, but as the temperature of SEMICONDUCTOR increases, the number of charge carriers increases, so the change in the resistance is different.
