Abstract
The universal expression of effective conductivity of weak non-linear media with the arbitrary current-voltage relation has been obtained ne ar the percolation threshold. For the case of strong nonlinearity j si milar to E-gamma, the critical behaviour of the effective conductivity calculated at the finite relation of conductivity, the violation of t he conductivity scaling is observed.
