WebYou can find more details about temperature coefficients of resistance here and a calculator here. The generic forumla for temperature affects on resistance is as follows: The temperature coefficient for some common materials are listed below (@ 20ºC): • Copper = 0.00393 • Aluminum = 0.004308 • Iron = 0.005671 • Nickel = 0.005866 WebTemperature Coefficient of Resistance (TCR) is the relative change of resistance value due solely to either the cooling or heating of the resistor. The following calculation will give the resistance value change based on the TCR of the resistor and amount of temperature difference. Enter your values.

WebTemperature Coefficient of Resistance (TCR, α R) This is a fixed value which is used to determine how much a change in temperature will affect the electrical resistance of a particular material. The coefficient defines the fractional change in resistance of a material per unit change in its temperature. Start Resistance (R 0) WebAt 300-400 K, a negative slope in the resistance-temperature dependence was observed with a thermal coefficient of resistance of (−10 ± 2) × 10 −3 K −1 for the asgrown film, and (−9 ± 1 ... byfield pottery
