Which of the following has a negative temperature coefficient of resistance?

(a) sensistor

(b) diode

(c) thermistor

(d) capacitor

The question was asked by my college director while I was bunking the class.

I would like to ask this question from Bias Compensation in division Transistor Biasing and Thermal Stabilization of Electronic Devices & Circuits

Best answer
Right choice is (c) thermistor

For explanation I would say: The thermistor has a negative temperature coefficient of resistance. It means, its resistance decreases exponentially with increasing T. The thermistor RT is used to minimize the increase in collector current.
