Thermistors which have a very high temperature co-efficient of resistivity belong to the class of solid called________________?
Correct answer: B. Semi conductors
- A. Dielectrics
- B. Semi conductors
- C. Insulators
- D. Conductors
Explanation
Thermistors are made from semiconductor materials whose resistance changes greatly with temperature. Conductors have relatively low temperature coefficients, while dielectrics and insulators are not the usual thermistor materials.
