When the temperature of an NTC (Negative Temperature Coefficient) thermistor increases, its resistance decreases. This behavior is due to the materials used in the thermistor, which allow more charge carriers to become available as temperature rises, leading to lower resistance. Consequently, NTC thermistors are commonly used in temperature sensing and circuit protection applications.

What electrical component decreases in resistance while increasing in temperature?
A thermistor is an electrical component that decreases in resistance as its temperature increases. Specifically, a negative temperature coefficient (NTC) thermistor exhibits this behavior, making it useful for temperature sensing and compensation in various electronic applications. As the temperature rises, the thermistor allows more current to pass through, effectively lowering its resistance.
Why does the resistance decrease in a thermistor when heated?
The resistance of a thermistor decreases when heated because it is a type of temperature-sensitive resistor made from semiconductor materials. As the temperature increases, more charge carriers (electrons or holes) are generated, enhancing the material's conductivity. This increase in charge carriers allows for easier flow of electric current, leading to a lower resistance. Thus, thermistors exhibit a negative temperature coefficient (NTC) behavior, where resistance decreases with rising 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
How does a thermistor effect the resistance of the temperature?
A thermistor is a type of temperature-sensitive resistor whose resistance changes significantly with temperature variations. Specifically, negative temperature coefficient (NTC) thermistors decrease in resistance as temperature increases, while positive temperature coefficient (PTC) thermistors increase in resistance with rising temperature. This property allows thermistors to be used in temperature sensing and control applications, enabling precise monitoring and regulation of temperature-dependent processes. Their sensitivity makes them suitable for various electronics, including temperature sensors and circuit protection devices.
How does negative temperature coefficient sensor work?
A negative temperature coefficient (NTC) sensor operates on the principle that its resistance decreases as temperature increases. Typically made from semiconductor materials, NTC sensors exhibit a significant drop in resistance when heated, allowing for precise temperature measurements. This change in resistance can be measured and translated into a temperature reading, making NTC sensors widely used in applications like thermistors and temperature monitoring systems. Their sensitivity and quick response time make them ideal for various industrial and consumer electronics.
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.
What electrical component decreases in resistance while increasing in temperature?
A thermistor is an electrical component that decreases in resistance as its temperature increases. Specifically, a negative temperature coefficient (NTC) thermistor exhibits this behavior, making it useful for temperature sensing and compensation in various electronic applications. As the temperature rises, the thermistor allows more current to pass through, effectively lowering its resistance.
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.

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.
