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.

**********************************
:-) THE THERMISTOR IS THE RESTOR WHOSE RESISTANCE INCRESE WITH DCREASE IN TEMPERATURE AND IT SHOW NEGATIVE COFFIECIENT OF TEMPERATURE THE THERMISTOR IS MAINLY SEMICONDUCTORS WHICH BEHAVE AS A INSULATER WHEN IT IS HEATED AND ACT AS A CONDUCTOR AT ZERO DEGREE CELCIUS
