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.
What is a negativ temperature co-efficient?
A negative temperature coefficient (NTC) refers to a type of thermistor where the resistance decreases as the temperature increases. This means that as the temperature rises, the electrical resistance of the NTC thermistor decreases, allowing more current to flow through it. NTC thermistors are commonly used in temperature sensing and compensation applications.
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.
What is a ntc thermistor?
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.
Why does resistance decrease as the NTC Resitor becomes warmer?
In NTC (Negative Temperature Coefficient) resistors, as the temperature increases, the number of charge carriers also increases. This results in more electron movement, decreasing the resistance. The relationship between temperature and resistance in NTC resistors is inversely proportional.

NTC thermistor
How the temperature of a thermistor affect the current which is able to flow in the circuit?
According to the different coefficient of resistance change, thermistors are divided into two types: positive temperature coefficient thermistor (PTC), whose resistance value increases with increasing temperature, and negative temperature coefficient thermistor Resistance (NTC), whose resistance value decreases with increasing temperature.

What is the relationship between resistance and temperature?
• ntc 'negative temperature coefficient': its resistance decreases as the temperature increases• ptc 'positive temperature coefficient': its resistance increases as the temperature increases
What is the value of band gap for thermistor?
NTC thermistors are metal oxide which has energap gap of the oder 0.5eV
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 difference between ntc and ptc?
NTC (Negative Temperature Coefficient) thermistors have resistance that decreases with increasing temperature, while PTC (Positive Temperature Coefficient) thermistors have resistance that increases with increasing temperature. NTC thermistors are commonly used for temperature sensing and control applications, while PTC thermistors are used for overcurrent protection and self-regulating heating elements.
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.
