Temperature coefficient of resistivity

For tungsten α = 45x10-3/ 176 C ρ = ρ 0 1 α T-T 0 = 55x10-7 Ωm R = ρL/A = 70 Ω note I suspect the ρ-T relation in reality may not be strictly linear over such a wide range of temperature my guess would be that the above value of α may only be valid for temperatures of tens to hundreds of 176 C In a few slides we...
