hey guys;
In the lep collider of geneva, there vagabond currents! I want to assess the effect of the vagabond currents on the beam energy! Therefore i only have one question:
The current starts at the rail and then he goes through the Earth to the collider. I only want to know how big the electrical resistance of this part of Earth is, when the distance between collider and rail is about 1 km. I also know the resistivity of Earth is [tex]100\Omega m [/tex]
I know: [tex]R=\rho \cdot \frac{l}{A}[/tex] but i don't know A!
What is it?
