Abstract
A short, general overview of non-linearity in electrical (current) response in two different regimes and their origins are discussed. Special attention is paid to some recent experiments on non-linear response in inhomogeneous (composite) materials. A model percolating structure to study this behavior has been introduced. Results for this model and some of its predictions for both do and ac non-linear response have been discussed.

Even in this semi-classical sense, these barriers are still fundamentally different from the Ohmic resistors since they contribute to the resistance but not to heat dissipation.

For quite high voltages, other more complicated situations (e.g., negative differential conductance) may arise, but we donot address them in our work discussed here.
This behavior is reminiscent of Daniel Bideau's movie on elastic networks under increasing strains (shown in the present Workshop) and discussed in the present volume.
