Vedclass · Answer

(C) In a semiconductor,the number of charge carriers (electrons and holes) increases exponentially with an increase in temperature.This leads to a decrease in the electrical resistance of the semiconductor material.According to Ohm's law,$I = V/R$. Since the voltage $V$ remains constant and the resistance $R$ of the semiconductor decreases,the current $I$ in the circuit will increase.

$A$ piece of semiconductor is connected in series in an electric circuit. On increasing the temperature,the current in the circuit will
