Direct determination of capacitance standards using a quadrature bridge and a pair of quantised Hall resistors

We describe measurements made using a quadrature bridge to simultaneously compare two quantum Hall resistors (QHRs) with two 10 nF capacitors at 1233 Hz. This direct approach eliminates uncertainties due to thermal and structural instabilities and to AC/DC differences of the wire resistors normally...

Description
Summary:We describe measurements made using a quadrature bridge to simultaneously compare two quantum Hall resistors (QHRs) with two 10 nF capacitors at 1233 Hz. This direct approach eliminates uncertainties due to thermal and structural instabilities and to AC/DC differences of the wire resistors normally used with an AC ratio bridge as an intermediary stage.
