Question

define temperature coefficient of resistance. and give it's SI unit​

Answer 1

Explanation:

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

Answer 2

Answer:

The SI unit of the temperature coefficient of resistivity is per degree celsius or (/°C) The unit of the temperature coefficient of resistance is ° Celsius Normally, the TCR (temperature coefficient of resistance) is consistent with a 20°C temperature. So normally this temperature is taken as normal room temperature.
