摘要：

We solve numerically the Boltzmann equation in the early universe in the presence of a constant electric field and find the electrical conductivity sigma in the range 1 MeV less than or similar to T less than or similar to M(w). The main contribution to sigma is shown to be due to leptonic interactions. For T less than or similar to 100 MeV we find sigma similar or equal to M(w) we obtain sigma similar or equal to 6.7T.
