The metal zinc has free electron concentration per unit volume, nv
, of 1.3×1029/m3
and an electron mobility μe
of 8×10−4 m2/V.s
. The charge carried by an electron, e
, is 1.6×10−19
coulomb. Based on this information, what is the electrical conductivity of zinc? Handbooks list the measured resistivity of zinc as 5.9μΩ.cm
. Is this consistent with your calculation? (Watch the units.)
