A thermistor is a semiconductor type of resistor in which the resistance is strongly dependent on temperature. The word thermistor is a portmanteau of thermal and resistor. The varying resistance with
Self-regulating heater
…comes from the tendency of such heating elements to maintain a constant temperature when supplied by a given voltage. PTC heating elements are a type of thermistor. PTC heating elements have large positive temperature coefficients of resistance, which means if a constant voltage is applied, the element produces a…
