Question

What do you mean by temperature coefficient of resistant ?

Answer 1

"The resistant-change factor per degree Celsius of temperature change is called the temperature coefficient of resistant. This factor is represented by the Greek lower-case letter "alpha"(a). A positive coefficient for a material means that its resistant increases with an increase in temperature."

Answer 2

Explanation:

• The resistance-change factor per degree Celsius of temperature change is called the temperature coefficient of resistance. ... A positive coefficient for a material means that its resistance increases with an increase in temperature. Pure metals typically have positive temperature coefficients of resistance.
