The precise ratio of the composite materials governs their resistance/temperature “curve.”. Increasing the temperature frees more electrons to carry the current and so the resistance falls. Aqa isa thermistor sources riekko de.
In This Fire Alarm Circuit, A Thermistor Works As The Heat Sensor.
At low temperatures, the thermistor has a high resistance. Isa thermistor aqa 2015 angugg de. A thermistor is a special type of resistor whose resistance decreases as its temperature increases.
A Thermistor (Or Thermal Resistor) Is Defined As A Type Of Resistor Whose Electrical Resistance Varies With Changes In Temperature.
Their resistance decreases as the temperature increases. Therefore very little current will flow. There are some disadvantages of thermistor which are given below.
