Introduction A thermistor is also a resistor whose resistance depends on temperature. A thermistor is a temperature-sensitive semiconductor component whose specific resistance changes rapidly with the changing of temperature. in another word, we can say that the resistance of the thermistor is changes when its temperature of its change. A thermistor is also called thermal […]
