Question

derive the equation for temperature coefficient of a resistance​

Answer 1

Answer:

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:-

Temperature coefficient of resistance is the measure of change in electrical resistance of any substance per degree of temperature change.

∆R ∝ Ro . t

∆R = αRo.t

Rt- ∆R = αRo.t

Rt = Ro ( αt +1)

αRot = Rt - Ro

α = ∆ R / Ro . t

This α is called temperature coefficient of resistance of that substance at 0 degree Celsius.
