Abstract
A quadrature bridge operating at a frequency of 1.233 kHz has been develope d to compare 10 nF capacitances to the quantized Hall resistance on the i = 2 plateau in order to realize the farad in terms of R-K. Portable precisio n ceramic capacitance transfer standards of remarkable performance have bee n developed for this purpose.
