Thermistor - Wikipedia
A 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 categorized based on their conduction models.

What is a Thermistor
There are two types of thermistors. NTC or Negative Temperature Coefficient thermistors, and PTC or Positive Temperature Coefficient thermistors. The difference is that NTC thermistors exhibit a DECREASE in resistance as body temperature increases, while PTC thermistors exhibit an INCREASE in resistance as body temperature increases.
What is a Thermistor? Types of Thermistors and Applications
Thermistors are used to control and maintain the temperature of a room for domestic and office use. They are used in automobiles to monitor the temperature. They are used for protection against overcurrent in electrical circuits and also act as a fuse. The Inrush thermistors are used for the safe starting of electrical motor.
How Does a Thermistor Work? Definition & Uses | Arrow.com
Nov 28, 2023 · The thermistor —short for thermally sensitive resistor—is a resistor that changes value with the temperature. Thermistors increase or decrease resistance with changing temperatures. Thermistors are broadly divided into two classes: The positive or negative temperature coefficient label refers to the k term in the first-order behavior approximation:
Types Of Thermistors And Its Applications - Electronics Hub
Sep 25, 2024 · Thermistors come in two main types: Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC). NTC thermistors exhibit a decrease in resistance as temperature rises, while PTC thermistors increase resistance as temperature goes up.
Thermistor: Construction, Working Principle, Types and
Jul 6, 2024 · 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. A thermistor is made of oxides of metals such as Nickel, Manganese, Cobalt, Copper, Uranium etc.
