Which of the following is NOT the salient feature of thermistors?

Which of the following is NOT the salient feature of thermistors? Correct Answer Thermistors are smooth.

Thermistors are generally made up of semiconductor materials.

Thermistors have a negative temperature coefficient of resistance i.e. the resistance decreases with an increase in the temperature.

Thermistors can measure the temperature in the range of -100°C to 300°C.

The basic circuit used for this purpose is shown below:

Advantages of thermistor:

  • It is rugged and compact.
  • It is inexpensive.
  • It has good stability.
  • It requires relatively simple and smooth circuitry.
  • The response time of a thermistor can vary from a fraction of a second to minutes, depending on the size of the detecting mass and capacity of the thermistor.
