Definition
A thermistor is a type of resistor whose resistance varies significantly with temperature, more so than in standard resistors. It is used for temperature measurement and control.
Etymology and Origin
The word thermistor is a blend of thermal and resistor, indicating its function and principle of operation. The concept dates back to the early 20th century, with the term itself being coined around the 1930s. The prefix “therm-” comes from the Greek “thermos” meaning “warm,” indicating its relation to heat, while “-istor” is derived from “resistor,” highlighting its electrical resistance properties.
