The thermistors are usually made of
metals with low temperature coefficient of resistivity
metals with high temperature coefficient of resistivity
metal oxides with high temperature coefficient of resistivity
semiconducting materials having low temperature coefficient of resistivity
As we learnt in
Thermistors are made of metal oxides with high-temperature coefficient of resistivity.
As we discussed in
Temperature dependent Resistivity -
-
thermistors are made of metal oxides with high-temperature co-efficient of resistivity.
