Webo. T0 = reference temperature. α = temperature coefficient of resistivity, units of ( oC)-1. For Ag, Cu, Au, Al, W, Fe, Pt, Pb: values of 3-5×10-3 (oC)-1. α are ~ Example: A platinum resistance thermometer uses the change in R to measure temperature. Suppose R0 = 50 Ω at T0=20 oC. α for Pt is 3.92×10-3 (oC)-1 in this temperature range.
