WebFrom that, we can calculate that those 1,000h operating at 100% rated power at 70°C are roughly equivalent (i.e. induce the same aging-related drift) to 31 months (2.583 years) at 100% rated power at 25°C, assuming the usual aging factor Q 10 = 2. That amounts to 1% over 2.583 years or an average 3,870 ppm/year at 25°C. WebSep 18, 2014 · Here you can find a table with various coefficients, and an online calculator. The relationship can be described by. Δ ρ = α ⋅ Δ T + ρ 0. where Δ ρ is the resistivity variation, α is the thermal coefficient for the material, Δ T is the temperature increase and ρ 0 is the original resistivity. The resistance of a conductor is.
