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