The resistive state in layered d-wave superconductors is studied using the quasiclassical Green's function approach. Similarity with a stack of Josephson junctions is found at small voltages. In the spatially uniform state differential conductivity at higher voltages becomes negative. In the nonuniform state the branch imbalance violates the Josephson relation.
