A NTC thermistor is a temperature sensor that has a "negative temperature coefficient". That means as temperature goes up, the resistance of the device goes down over it's operating range.

Operating range of ntc and ptc thermistor?
That depends on which units we are using. They are models that cover a variety of ranges.
What is the working principle of the thermistor?
A thermistor changes it's resistance depending on temperature. Hence Thermal-Resistor. (Thermistor) It is all to do with the crystal structure of the substance the thermistor is made of. Some increase their resistance as temperature rises, called Positive Thermal coefficient, 'PTC'. Others reduce their resistance with increasing temperature, called Negative Thermal Coefficient. 'NTC'. They can be used in a feedback loop of a simple amplifier and switch circuits, to control temperature of a device. They can be calibrated for use in a current loop, to directly measure temperature, like a thermometer. They can be used to stop surges in start up circuits, initially giving a high resistance until things warm up. Or used to apply a large current and then reduce as things warm up. (Like in the old degaussing coils on a colour CRT).
What is the relationship between current and voltage in a thermistor?
V=IRR changes as a result of the change in temperature.
How could a thermistor be used to determine airflow in cubic feet per minute - a thermistor measures temperature changes - how do you change that to cubic feet per minute?
You must have your foudation cubic feet per min first. Then using the thermistor measure the temperature and it should hold steady. The fluctuations in the resistance will show degradations in the airflow. More ohms the less airflow. So Temp % resistance = x Airflow =r known computed airflow =f ix= diff r/f okay. i think i understand.
What is the difference between PTC and NTC resistors?
positive temperature coefficient vs. negative temperature coefficient resistance increases or decreases with increase of temperature, respectively.
What equipment is used in kidney dialysis?
NTC thermistor
Is a NTC thermistor different from PTC thermistor?
Yes, NTC stands for Negative temperature coefficient. This means the resistance goes down as temperature goes up. A PTC has a positive temperature change. As temp goes up, the resistance will increase also.
Operating range of ntc and ptc thermistor?
That depends on which units we are using. They are models that cover a variety of ranges.
What is the value of band gap for thermistor?
NTC thermistors are metal oxide which has energap gap of the oder 0.5eV
Why does the resistance of a thermistor change when you change its temperature?
The resistance of a thermistor changes when its temperature changes due to the inherent properties of the thermistor material. In a negative temperature coefficient (NTC) thermistor, the resistance decreases as the temperature increases, whereas in a positive temperature coefficient (PTC) thermistor, the resistance increases as the temperature rises. This change in resistance is caused by the variation in the number of charge carriers (electrons or holes) and their mobility within the material as temperature changes.
Fullform of ntc and ptc?
ntc: negative temperature coefficient ptc: positive temperature coefficient
What year was the NTC website set up?
The NTC website was setup in the year 2011. The NTC was used as the road-map for the transition of the country to a constitutional democracy and elected government.
What kind of thermometer has a thermistor at its end?
A RV absorption refrigerator uses a thermistor as a thermostat. The thermistor is moved up or down to regulate the refrigerator temperature.

What does ntc 82 c mean on a thremostat?
NTC is the brand name. And 82C means it has a rating of 82 degrees centigrade.
What is the difference between thermostat and thermistor?
one is called a thermostat and the other is called a thermistor - Ross Henderson
