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.
Temperature coefficient of resistance is the measure of change in electrical resistance of any substance ... Let a conductor having a resistance of R0 at 0oC and Rt at toC respectively.
