Question

what are thermistors?

Answer 1

A thermistor is a heat sensitive resistor usually prepared from oxides of various

metals such as nickel, copper, cobalt, iron etc. These compounds are also semi-conductor. For thermistors alpha is very high which may be positive or negative. The resistance of thermistors changes very rapidly with

change of temperature.
