How does a thermistor work bbc
WebThe external property that changes in thermistors as a function of temperature is the resistance. R goes up or down with increased temperature, depending on the kind of thermistor you have. Most things just called a "thermistor" exhibit decreased resistance with rising temperature. WebThe Thermistor is a solid state temperature sensing device which acts a bit like an electrical resistor but is temperature sensitive. Thermistors can be used to produce an analogue output voltage with variations in ambient temperature and as such can be referred to as a …
