Vedclass · Answer

(B) In a semiconductor,the number of free charge carriers (electrons and holes) depends on the temperature. As the temperature decreases,the thermal energy available to break covalent bonds decreases,leading to a reduction in the number of charge carriers.Since the resistance $R$ of a semiconductor is inversely proportional to the number of charge carriers,a decrease in temperature results in an increase in resistance.Therefore,when a semiconductor is cooled from $T_1 \ K$ to $T_2 \ K$,its resistance will increase.

$A$ semiconductor is cooled from $T_1 \ K$ to $T_2 \ K$. Its resistance:
