## What does a thermistor do in a circuit simple?

Thermistors are thermally sensitive resistors whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body temperature.

What is a thermistor for kids?

A thermistor is a type of resistor used to measure temperature changes, relying on the change in its resistance with changing temperature. If k is negative, the resistance decreases with increasing temperature, and the device is called a negative temperature coefficient (NTC) thermistor.

What is a thermistor in science?

Thermistor. Thermistors are used as temperature sensors, for example, in fire alarms. In the most common type of thermistor, the resistance decreases as the temperature increases: at low temperatures, the resistance of a thermistor is high and little current can flow through them.

### Which of the following is correct for thermistors?

Which of the following is correct for thermistors? Explanation: For thermistors as temperature increase, resistance decreases. 10.

What appliances use thermistors?

Thermistors are used as temperature sensors. They can be found in every day appliances such as fire alarms, ovens and refrigerators. They are also used in digital thermometers and in many automotive applications to measure temperature.

What is thermistor simple?

A thermistor is a resistance thermometer, or a resistor whose resistance is dependent on temperature. The term is a combination of “thermal” and “resistor”. With an NTC thermistor, when the temperature increases, resistance decreases. Conversely, when temperature decreases, resistance increases.

#### What are thermistors explain the working construction and applications of thermistors?

A thermistor (or thermal resistor) is defined as a type of resistor whose electrical resistance varies with changes in temperature. Although all resistors’ resistance will fluctuate slightly with temperature, a thermistor is particularly sensitive to temperature changes.

Is RTD a thermistor?

The Resistance Temperature Detector (RTD) and Thermistor are the temperature sensitive devices used for the measurement of temperature. The RTD is also called a resistance thermometer is a wire coil made up of metals (platinum, copper, or nickel). Whereas a thermistor is a thermal resistor composed of metal oxides.

What are the materials used in thermistors?

Thermistors are made from semiconductor materials, typically metallic oxides, using cobalt, manganese, or nickel.
