Deatiled mapping of time average and fluctuating component of voltages generated by transport current in HTSC screen-printed films and single crystals were performed as a function of temperature, external magnetic field and transport current densities. Sign change of transversal voltage are shown to be a universal characteristic in two systems while spatial correlations of voltage fluctuations had marked difference.
