What is Thermistor? - Definition, Types, Construction, …

WebThis is how NTC thermistors operate. Temperature and resistance have an inverse relationship. PTC Thermistor Resistance. Positive temperature coefficient (PTC) thermistors are thermistors whose resistance value increases when the temperature they are exposed to increases. It's a direct relationship. As temperature goes up, resistance … WebSince the negative temperature coefficient of silver sulphide was first observed by Michael Faraday in 1833, there has been a continual improvement in thermistor technology. The most important characteristic of a thermistor is, without question, its extremely high temperature coefficient of resistance. WebAt the resistance / temperature characteristics of positive thermistors “Posi-R”, the temperature which the resistance value becomes twice as high as that of at 25˚C, is called as “switching temperature” (Curie point) Thermistors “Posi-R” show anomalous temperature characteristics of resistivity, and typical characteristics are represented in Fig. 1. get xbox game pass ultimate for cheap
