Thermistor, which has high temperature co-efficient of resistivity, is used as the sensing element in resistance thermometer. It is a/an ?
Correct answer: C. Solid semi-conductor
- A. Insulator
- B. Conductor
- C. Solid semi-conductor
- D. Liquid semi-conductor
Explanation
A thermistor is made from semiconductor materials whose electrical resistance changes strongly with temperature. It is therefore a solid semiconductor, not a conventional conductor or liquid semiconductor.
