NiChrome 60 Cold Daw wire Dia. 8.0mm-0.05mm, Electric Resistivity: 1.11×10-6Ω.m at 20oC, cm2/Ω= (W is Surface area loading)

How to get Electric Resistivity at Operating Temperature?

Ct = Temperature-Resistance Factor
Rt = Electric Resistivity at operating temperature
R = Electric Resistivity at 20oC

Rt=R×Ct
