Abstract :
A quadrature bridge for comparison of two 12,906.4035 Ohm quantized Hall resistors (or two resistance standards) and two 10000 pF capacitors is described. The bridge has two identical current circuits and allows one to connect directly the potential leads of the four-terminal impedances to be compared.
