{title2=$L=K_e/(\sigma T)$}

The <Lorenz number> is the ratio $L=K_e/(\sigma T)$. The Sommerfeld value $L_0=(\pi^2/3)(k_B/e)^2\simeq2.44\times10^{-8}\,\mathrm{W\,\Omega\,K^{-2}}$ applies under the assumptions of the <Wiedemann-Franz law>. The ratio must use electronic <thermal conductivity> if lattice heat flow is appreciable.
