| Zusammenfassung | We present improved results for the ac longitudinal resistance at the high-potential side of a quantum Hall device. Previous measurements indicated a different frequency- and current-dependence at either side of a device. This asymmetry is now attributed to a loading effect which has been overlooked. When the measuring bridge is modified to eliminate this effect, the ac longitudinal resistances at the high- and the low-potential side show a very similar and consistent behaviour. |
