Homework Statement

How do i estimate the von-klitzing constant based on figure 2

Relevant Equations

Rk = h/e^2 (von-klizing constant)

Hi all,

Given that the question:

From what i know

, I am not sure how this equation can help me estimate the von-klitzing constant? Or is there another way? Thanks!

The answer to this question is that the von-Klitzing constant cannot be estimated using an equation. It is a fundamental constant of nature and must be measured experimentally. The exact value of the constant is 8.854187817 × 10^−12 A⋅s/Vm.
