    A the r mister is dipped in a water bath. As the temperature increases the current in the thermistor also increases. This is due to decrease in

    A)  resistivity

    B)  conductivity

    C)  reactance

    D)  capacitance

    Correct Answer: A

    Solution :

                    The temperature coefficient of resistivity for thermistor is negative. So, with the increase in temperature, the resistivity of thermistor decreases.
