What is the Temperature Coefficient of Resistance?The temperature coefficient of resistancemeasures changes in the electrical resistance of any substance per degree of temperature change.Let us take a conductor having a resistance of R0 at 0oC and Rt at toC, respectively.From the equation of resistance variation with temperature, we getThis αo is called the temperature coefficient of resistance of that substance at 0oC.From the above equation, it is clear that the change in electrical resistance
