WebMar 22, 2024 · How does the thermistor work: Thermistors can get further classified as the Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC). In NTC, when the resistance lessens, the thermal reading increases. In PTC, the thermal reading increases with resistance. This function helps in a fuse. WebA thermistor is a semiconductor type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word thermistor is a portmanteau of thermal and resistor . Thermistors are divided based on their conduction model.
