The dependences of the active resistance of a number of dielectric-conductor composites on the frequency of the applied voltage in the range of less than one megahertz are experimentally investigated. It is shown that the frequency dependence of the active resistance in dielectric-conductor composites with non-magnetic material is small and is limited by the effect of the skin effect, and in composites with ferromagnetic resistivity decreases by one or two orders of magnitude with increasing frequency.
