noun Electronics.

1. a resistor whose action depends upon changes of its resistance material with changes in temperature.

noun

1. a semiconductor device having a resistance that decreases rapidly with an increase in temperature. It is used for temperature measurement, to compensate for temperature variations in a circuit, etc

1. A resistor whose resistance varies as a function of temperature. Thermistors are used in electrical devices such as thermometers and thermostats that measure, monitor, or regulate temperature. See more at resistor.
