WebJan 26, 2024 · Thermistors act as a passive component in a circuit. They are an accurate, cheap, and robust way to measure temperature. While thermistors do not work well in extremely hot or cold temperatures, they are the sensor of choice for many different applications. Thermistors are ideal when a precise temperature reading is required. WebA thermistor is an electrical component in which the resistance decreases as the temperature increases. It has the following symbol: At low temperature the thermistor has a high resistance and little current can flow through it. But at high temperatures the resistance of the thermistor is low and more current flows through it. WebA thermistor's operation is a function of the electron-hole pair theory. As the temperature of the semiconductor rises, the electron-hole pair generation increases (due to thermal agitation). Increased electron-hole pairs causes a drop … cryptocrisis
