Resistivity, Temperature Calculator:
Resistivity increase or decrease significantly as temperature changes.
The relationship between resistivity and temperature is:
Δρ = α * ΔT * ρ0
Δρ : Change of the resistivity
α : Resistivity, temperature coefficient
ΔT : Change of temperature
ρ0 : Original resistivity
For example, at 20 °C (293 K), the resistivity of Copper at 20 °C is 1.68 * 10-8 , it's temperature coefficient is 0.0039 K-1, its resistivity at 30 °C is 1.75E-8.
