The von klitzing constant

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.
