Abstract :
The design and evaluation of different bridges used for ac quantized Hall resistance (ac QHR) measurements at NRC, METAS and PTB are presented. These bridges are used to study the frequency, magnetic field intensity, and current dependence of quantized Hall, (RXY ), longitudinal, (RXX), resistances, as well as conventional ac resistors
