Thermistor is a PTC resistor. Its ohmic value directly proportional to the temperature. Yogeshwari is correct only. Ravikumar answer only wrong.

Sireesha said:   1 decade ago
If temperature increases then resistance value decreases means it is a negative temperature coefficient.

Thermal + resistance. Resistance of thermister varies with temperature having -ve temp coefficient.

Raju said:   1 decade ago
Thermistors is a type of resister whose resistances varies significantly with temperature. Temperature increasing resistances decreasing.

Here name it self specifies that thermistor is a temperature varing device.

Thermal+resister->thermistor.

Ravikumar said:   1 decade ago
Thermistor is not a positive temperature coefficient. Its an NTC.

"Negative Temperature Coefficient". (ie) If temperature increases the resistor value starts to decrease. Yogeshwari answer is wrong.

Thermally sensitive resistor is known as thermistor.

Yogeshwari mahanti said:   1 decade ago
Thermister is the positive temperature cofficient so that
thermister is the temperature sensitive.

Uma maheswararao said:   1 decade ago
Here sensitive means temperature effects highly in huge amounts. Thermister can have that property.

This is type of resistor used to calculate tempreture, this resistor is specialy design for temp measurement.
