Thermistors are usually made of (a) metal oxides with high temperature coefficient of resistivity (b) metals with high temperature coefficient of resistivity (c) metals with low temperature coefficient of resistivity (d) semiconducting materials having low temperature

Answer: (a). A thermistor must change resistance strongly with temperature. It is made of metal oxides (e.g. of Ni, Mn, Co) which have a high temperature coefficient of resistivity. So the answer is (a).
