“…[47]- [49]. The QHR system can either work conventionally with a single chip at a fixed i value [4] or be operated in multiple connecting arrays to realize a fixed value of quantum resistance [50], [51]. Recent advances in graphene material research make a QHR standard possible to be operated in a lower magnetic field, higher operating temperature, and higher current density [52]- [54].…”

A milestone revision of the International System of Units (SI) was made at the 26th General Conference on Weights and Measures that four of the seven SI base units, i.e. kilogram, ampere, kelvin, and mole, are redefined by fundamental physical constants of nature. The SI base unit founding the electrical measurement activities, i.e. ampere, is defined by fixing the numerical value of the elementary charge to e = 1.602 176 634 × 10 −19 C. For electrical measurement, several major adjustments, mostly positive, are involved in this SI revision. In this paper, the main impacts of the new SI for electrical measurement activities are surveyed under the new framework.

“…In the earlier decades of developing QHR standards, the many NMI efforts had succeeded in implementing new standards based on GaAs devices [34][35][36][37][38][39][40][41][42][43], and metrologists commenced to explore the extent to which these devices could accommodate other values of resistance, namely through the construction of quantum Hall array resistance standards (QHARS) [44][45][46][47][48][49][50][51][52]. In conjunction, pursuits of standardized impedances from the QHE were well on their way at various NMIs to avoid using a difficult-to-construct calculable capacitor [53][54][55][56][57][58][59][60][61][62].…”

The quantum Hall effect (QHE), and devices reliant on it, will continue to serve as the foundation of the ohm while also expanding its territory into other SI derived units. The foundation, evolution, and significance of all of these devices exhibiting some form of the QHE will be described in the context of optimizing future electrical resistance standards. As the world adapts to using the quantum SI, it remains essential that the global metrology community pushes forth and continues to innovate and produce new technologies for disseminating the ohm and other electrical units.

To propose a structure of high-accuracy shunt resistors, the frequency and current dependencies of ac shunt resistors with different rated current are evaluated both of ac resistance and phase angle. To evaluate these characteristics, modified current-bridge method was developed. The ac resistances of the shunts do not vary considerably with the frequency, up to 3 kHz. The phase angle of ac shunts varies proportionally to the frequency. The current dependence of the ac resistance of shunts seems to change with current value. The current dependence of the phase angle of the shunt remain stable up to 10 A. Keywords
