Conductivity of Semiconductor | Electrical4U
It is well known to us that the conductivity of a material depends on the concentration of free electrons in it. Good conductors consist large concentration of free electrons whereas insulators consist small concentration of free electrons. These conductors have a high conductance value (and hence a low resistance value). value).
