"Temperature coefficient" means, how does a certain physical quantity vary, depending on the temperature. In this case, the physical quantity in question is probably the electrical resistance, or the electrical resistivity.

How semiconductors behaves at absolute temperature?
As temperature increases the resistance of semiconductors decreases. This means that semiconductors have a negative temperature coefficient.
How diffusion coefficient depends on temperature?
The diffusion coefficient depends on temperature in direct negative exponent.
Coefficient of Temperature depends on?
Temperature depends on the average kinetic energy of atoms and molecules.
Which material has nearly zero temperature coefficient?
nickel Constantly
Does juice temperature increase with increasing convective heat transfer coefficient at any constant kettle surface temperature?
Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.
Does porcelain have a nearly zero temperature coefficient of resistance?
Porcelain is an insulator, its resistance approximates infinity.
How semiconductors behaves at absolute temperature?
As temperature increases the resistance of semiconductors decreases. This means that semiconductors have a negative temperature coefficient.
What are mica?
A: Mica is an insulator used extensively in capacitors and hi quality Transformers. It has very good temperature coefficient
What are mica products?
A: Mica is an insulator used extensively in capacitors and hi quality transformers. It has very good temperature coefficient
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.
Is resistivity of a conductor temperature dependent?
A perfect insulator has infinite ohms of resistance.
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.
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.
How the coefficient of viscosity of a liquid changes with temperature?
The coefficient of viscosity of liquids decreases with an increases in temperature.
Does a safe reactor have a positive or negative 'temperature coefficient of reactivity'?
negative 'temperature coefficient of reactivity'
Fullform of ntc and ptc?

How diffusion coefficient depends on temperature?
The diffusion coefficient depends on temperature in direct negative exponent.
