ABSTRACT

If we take a 1Ω sample of copper at 0 °C, and increase its temperature by 1 °C, its resistance will increase by 0.004Ω to 1.004Ω. e value 0.004 Ω/Ω/°C is the temperature coecient, a, of copper.

Every material has a dierent coecient, but the most common conducting materials have values ranging between 0.0039 and 0.0045 Ω/Ω/°C.
