So I am doing elementary physics, as in high school elementary, and learned that the equation for the resistance of a wire can be put in the form: [tex]\rho\frac{\ell}{S}[/tex]
so what about a wire that is in the form of a sphere? (let's say something like that can exist :), or you can prove to me that it can not ;) )
