Which material is a poor heat conductor?A. IronB. SilverC. WoodD. Copper International Annealed Copper Standard (IACS) pure =1.7×10 −8 Ω•m =58.82×10 6 Ω −1 •m −1. For main article see: Copper in heat exchangers. The TPRC recommended values are for well annealed 99.999% pure copper with residual electrical resistivity of ρ 0 =0.000851 μΩ⋅cm. TPRC Data Series volume 1 page 81. List of thermal conductivities - Wikipedia Electrical resistivity and conductivity - Wikipedia Electrical resistivity and conductivity - Wikipedia Skin effect is the tendency of an alternating electric current (AC) to become distributed within a conductor such that the current density is largest near the surface of the conductor and decreases exponentially with greater depths in the conductor. The electric current flows mainly at the "skin" of the conductor between the outer surface and a level called the skin depth. Heat transfer occurs at a lower rate in materials of low thermal con...
