The effect of increase in temperature on the number of electrons in conduction band ($\mathrm{n_e}$) and resistance of a semiconductor will be as:

Question

$\mathrm{n}_{\mathrm{e}}$ decreases, resistance increases

Both $\mathrm{n}_{\mathrm{e}}$ and resistance increase

$\mathrm{n}_{\mathrm{e}}$ increases, resistance decreases

Both $\mathrm{n}_{\mathrm{e}}$ and resistance decrease
