Dynamic transport properties of the layered high temperature, anisotropic oxide superconductors are investigated. An analysis is performed describing in which way resistivity-less transport current flow in these superconductors is limited depending on the velocity of the vortex motion, creating the resistivity, which determines the critical current. The specific anisotropic shape of the vortices is considered in connection with the layered crystal structure of the high temperature oxide superconductors taken into account. The results of the numerical calculations of the current-voltage characteristics in such case are presented, indicating in the nearest neighbours approximation the influence of anisotropy and inter-plane interaction on the critical current. The elastic energy of the vortex lattice is also included.
