Abstract
A systematic investigation of the current and frequency dependence of the quantum Hall resistance (QHR) and of the longitudinal resistivity has been carried out at low temperature at the center of the plateau i=2. The deviation of the QHR from the von Klitzing constant is found to be proportional to the longitudinal resistivity and extrapolates to zero, within the measurement uncertainty, when the dissipation in the two-dimensional electron gas vanishes.
