    A piece of semiconductor is connected in series in an electric circuit. On increasing the temperature, the current in the circuit will                                                                          [RPMT 2003]

    A)            Decrease                               

    B)            Remain unchanged

    C)            Increase                                 

    D)            Stop flowing

    Correct Answer: C

    Solution :

               Because with rise in temperature, resistance of semiconductor decreases, hence overall resistance of the circuit increases, which in turn increases the current in the circuit.
