Thermistor is a kind transducer which converts thermal energy into electrical energy.

Thermistor is special type of resistor.

1. When temperature is increased resistance decrease.
2. When resistance is increase temperature is decrease.

How to calculate the value of thermistor in airflow detector circuit?

Thermister can be of two types depending temperature coefficient, k.

If k is negative thermister is then called NTC or negative temp. Coefficient thermistor. And if, k is positive PTC thermistors.

Thermister are used to measure temperature. And this type of resistor used to calculate temperature.

Thermistor contain a variable resister. The resister value vary according to the variation on temperature.

Temperature =1/resistor.

Because thermister having thermal property and which the component very sensitive due to some radiation which is by using anti static room.

Yes, @Manoj is correct.

Thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor. Thermistors are widely used as inrush current limiter, temperature sensors. Thermistors are of two opposite fundamental types:.

With NTC, resistance decreases as temperature rises to protect against inrush overvoltage conditions. Commonly installed in parallel as a current sink.

With PTC, resistance increases as temperature rises to protect against overcurrent conditions. Commonly installed in series as a resettable fuse.
