Solution

The correct option is D All the above
A thermistor is a type of resistor whose resistance depends on temperature, more than in standard resistor. The word is a combination of thermal and resistor. They are widely used as inrush current limiters, temperature sensors, self -resetting overcurrent protectors, and self-regulating heating elements.
It is made up of semiconductors and has a negative temperature coefficient of resistance.

Q. Consider the following statements A and B and identify the correct answer :
A : Thermistors can have only negative temperature coefficients of resistances.
B : Thermistors with negative temperature coefficients of resistance are used as resistance thermometers, to measure low temperatures of the order of 10 K.

Q. Assertion :A pure semiconductor has negative temperature coefficient of resistance. Reason: In a semiconductor on raising the temperature, more charge carriers are released, conductance increases and resistance decreases.
