Step 1

1 of 5The von Klitzing constant is given by the following equation

$\begin{align} R_K=\frac{h}{e^2}, \end{align}$

in which $h$ is given in joule-seconds, $\mathrm{Js}$, and $e$ is given in coulombs, $\mathrm{C}$.

We have to show that $R_K$ gives the SI unit for resistance (the ohm). To do that we will be looking at the definitions of $\mathrm{C}$ and $\mathrm{J}$.
