Download Solution PDFThermistor:
- It is a semiconductor that changes resistance with a change in temperature.
- The thermistor resistance is inversely proportional to the temperature.
- When the temperature decreases, the resistance of the thermistor increases (NTC: Negative Temperature Coefficient).
- It is mostly used in modern package air-conditioners and other electronic expansion valves.
- Sometimes it is used as an anti-frost device also.
