Q. A thermister is dipped in a bath whose temperature is to be measured. When the temperature increase the current also increase, because of decreases in
A) Capacitance
B) Reactance
C) Resistance
D) Resistivity
Explanation
(d) The temperature coefficient of resistivity for thermister is negative. Therefore by increase in temperature the resistivity of the thermister decreases.
