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 temperature allows these devices to be used as temperature sensors, or to control current as a function of temperature. Some thermistors have decreasing resistance with temperature, while other types have increasing resistance with temperature. This allows them to be used for limiting current ... Thermistors come in various types, each with unique features. Explore their diverse applications in temperature sensing and control systems. The Thermistor or simply Therm ally Sensitive Res istor is a temperature sensor that works on the principle of varying resistance with temperature. They are made of semiconducting materials. The circuit symbol of the thermistor is shown in the figure. Construction of Thermistor A thermistor is made of oxides of metals such as Nickel, Manganese, Cobalt, Copper, Uranium etc. It is available in a variety of shapes and sizes. Commonly used for configurations are Disk type, Bead type and Rod type ... Learn what is thermistor , a temperature sensitive resistor that changes its resistance with temperature. Find out the types, construction, resistance temperature characteristic and advantages of thermistor .
