WebThere are many physical constants in science, some of the most widely recognized being the speed of light in vacuum c, the gravitational constant G, the Planck constant h, the electric constant ε0, and the elementary charge e etc. For example, 6.02214 x 10²³ mol-1 is the value of Avogadro's number, it remains the same everywhere. Webwhere the von Klitzing constant R K is believed to be equal to h/e2, and i is an integer of the quantum Hall state. The value of the U. S. representation of the ohm is consistent with the conventional value of the von Klitzing constant, i. e., R K-90 exactly, adopted internationally for use in representing the ohm beginning January 1, 1990.

WebJan 7, 2010 · The product of two empirical constants, the dimensionless fine-structure constant (α) and the von Klitzing constant (R k, an electrical resistance), turns out to be an exact dimensionless number. Then the accuracy and cosmological time variation (if any) of these two constants can be tied together. Also this product defines a natural unit of the … Webconstant is h/[(1/2)ge]e which under special conditions becomes h/e2 which is the von Klitzing’s constant.
