We studied the nonlinear behavior in the electrical resistance of various correlated insulators. We found that, irrespective of the origin of the insulating state, the resistivity starts decreasing above a critical field Ec, which hardly depends on the temperature and the compound, at a time scale of less than microseconds. This universal behavior in the nonlinear resistivity is discussed on the basis of percolation conduction in a disordered system. We also discuss a substantial decrease in the resistance at the longer time scale of milliseconds.
