Vedclass · Answer

(C) In semiconductors,the energy gap between the valence band and the conduction band is small. As the temperature increases,more thermal energy is available to the electrons in the valence band. This allows more electrons to overcome the energy gap and jump into the conduction band. Consequently,the number of free electrons in the conduction band increases,which leads to an increase in conductivity and a decrease in resistance. Therefore,the correct statement is that the number of electrons in the conduction band increases.
