What Materials that have positive temperature coefficient?
Some materials with a positive temperature coefficient of resistance include silicon, germanium, and thermistors made of certain metal oxides like manganese, cobalt, and copper. These materials exhibit an increase in resistance with an increase in temperature, making them useful in temperature-sensing applications.
How the resistance of conducting material vary with temperature?
Well, there's typically two types of materials-Those with positive temperature coefficient and those with negative temperature coefficient. Positive temperature coefficient are those whose resistance increases as temperature increases. Negative temperature cofficient are those whose resistance decrease when the temperature increase. There are however some alloys such as Manganin& Constantan whose resistance is not affected by temperature
Fullform of ntc and ptc?
ntc: negative temperature coefficient ptc: positive temperature coefficient
Does a safe reactor have a positive or negative 'temperature coefficient of reactivity'?
negative 'temperature coefficient of reactivity'
What do you mean positive temperature co-efficient and negative temperature co-efficient of temperature?
A positive temperature coefficient means that the resistance of a material increases as temperature increases. Conversely, a negative temperature coefficient means that the resistance decreases as temperature rises. These coefficients are important in understanding how materials respond to changes in temperature and are commonly seen in the properties of semiconductors and resistors.
What is the temperature coefficient of an extrinsic semiconductor is?
positive
What is the difference between positive and negative temperature coefficient of resistance?
Negative temperature coefficient of resistance means that as the temperature of a piece of wire or a strip of semiconducting material increases, the electrical resistance of that material decreases.
What is the temperature coefficient of extrinsic semiconductor?
positive
Do The resistance of a material generally increases as its temperature increases?
The answer to this depends on the material from which the resistance is made. For most materials resistance increases with increasing temperature. This is referred to as having a "positive temperature coefficient". Some materials have a negative temperature coefficient; these do have uses in electronics.
What happens when the temperature of a forward biased diode is increased?
What happens depends on the temperature coefficient of the diode. If that diode has a positive temperature coefficient, it resistance increases with increased temperature. A diode with a negative temperature coefficient does the opposite.
Why does the resistance of a thermistor decrease as the temperature rises?
Some materials have negative temperature coefficients of resistance, and some have positive temperature coefficients. Carbon is an example of a substance with a negative thermal coefficient of resistance, so it's resistance will decrease as it gets hotter.
What Materials have a negative temperature coefficient?
Glass, Ceramics, Semiconductors
