Abstract :
This paper summarizes the construction and operation of our quadrifilar resistor and newly developed precision AC resistance ratio bridge with relative uncertainty of about a few parts in 10/sup 8/. The quadrifilar resistor is used as the resistance transfer standard from DC to about 10 kHz frequency range. However, its frequency dependence is usually certified only by calculation based on the Gibbing´s theory. We report our plan to evaluate the correctness of calculations by comparing its frequency dependence to that of a bifilar resistor using the AC resistance ratio bridge.
