Question

Define temperature coefficient of a resistance and give its units​

Answer 1

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.

The definition is explained as follows :

The SI unit of temperature coefficient of resistance is  

Explanation:

The quantity that is used to find the change in electrical resistance of any substance per degree of temperature change is called the temperature coefficient of resistance. Its relation concerning for to resistance is given by :

$\bold{\triangle R/R_0=\alpha \triangle T}$

Where:

$R_0$ is initial resistance,

$\alpha$ is the temperature coefficient of resistance

The SI unit of temperature coefficient of resistance is
