Question

Difference between thermistor and sensistor resistors

Answer 1

Thermistor: Negative temperature coefficient

Sensistor: Positive temperature coefficient.

In semiconductors as temperature increases conductivity increases i.e., it can exhibit positive temperature coefficient of conductivity, this property finds applications in control devices, as a thermal relay etc., Such a semiconductor is called as thermistor.

Sensistor is a heavily doped semiconductor which exhibits positive temperature coefficient of resistance.
