New realization of the ohm and farad using the NBS calculable capacitor

Results of a realization of the ohm and farad using the US National Bureau of Standards (NBS) calculable capacitor and associated apparatus are reported. The results show that both the NBS representation of the ohm and the NBS representation of the farad are changing with time, Omega /sub NBS/ at th...
