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.
When the temp of an NTC thermistor increases its resistance will?
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 is an application for a positive temperature coefficient ptc thermistor device?
A positive temperature coefficient (PTC) thermistor is commonly used in overcurrent protection applications, such as in electrical circuits and power supplies. When the temperature rises due to excessive current, the resistance of the PTC thermistor increases sharply, limiting the current flow and preventing damage to the circuit. Additionally, PTC thermistors are utilized in heating applications, such as self-regulating heating elements, where they provide consistent temperature control by adjusting resistance with temperature changes.
How does resistivity depends on temperature of conductors?
The resistance of a simple conductor normally rises as its temperature rises.
Does the resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
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.

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 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.

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).
How does temperature affect the resistance of conducting materials?
As temperature increases, the resistance of conducting materials also typically increases. This is because as temperature rises, the atoms in the material vibrate more, leading to more collisions with electrons, which in turn increases resistance. Conversely, as temperature decreases, resistance tends to decrease as well.
