Temperature Coefficient of Resistance ①
In any material, the resistance of that material will change as the temperature changes. This extends to resistors as well. The rate of resistance change based on temperature is referred to as the Temperature Coefficient of Resistance. It is indicated in units of ppm/C and determined from the resistance change from the reference temperature and the change in temperature.
