WebJul 25, 2022 · The conductivity (σ) of a metal, which is the inverse of \(\rho\), is proportional to μ, which in turn is proportional to τ (and λ): \[\mathbf{\sigma = ne\mu = \frac{ne^{2}\tau}{m_{e}}}\] We can use this equation to work out the conductivity of a specific metal (Cu), for which n = 8.5 x 10 22 cm -3 and τ = 2 x 10 -14 s.
