A thermistor differs from an ordinary resistance in the following ways. (i)The resistivity and hence the resistance of thermistor changes very rapidly with change of temperaure. (ii) The temperature coefficient of resistivity of thermistor is very high. (iii) The temperature coefficient of resistivity of thermistor can be both, positive and negative.
