The effect of increase in temperature on the number of electrons in conduction band ($n_e$) and resistance of a semiconductor will be as
Answer: (C) $n_e$ increases, resistance decreases
Heating breaks more covalent bonds, so more electrons reach the conduction band: $n_e$ increases and the resistance decreases.
