What is thermistor? How it is used in Wheatstone Bridge?
What is thermistor: It is a passive temperature transducer so battery must be used in its circuit. Thus a thermistor is a transducer which changes its resistance due to change in temperature.
Thermistor is a temperature-sensitive resistor that come in two types: NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient). NTC thermistors decrease in resistance as temperature rises, while PTC thermistors increase resistance with temperature. These characteristics make thermistors widely used in temperature sensing, circuit protection, and control applications, offering essential functionality in a variety of electronic systems.
