A thermistor is a type of temperature sensor that changes its electrical resistance based on temperature variations. This unique property allows thermistors to be used for precise temperature measurements and control in various applications, including electronics, automotive, and industrial processes. They are categorized into two main types: NTC (Negative Temperature Coefficient) thermistors, which decrease in resistance as temperature increases, and PTC (Positive Temperature Coefficient) thermistors, which increase in resistance with rising temperature.
congrats on reading the definition of thermistor. now let's actually learn it.
