deos this mean that in direct, non varying current, the conductivity/resistance is equal on the surface and in any point in the cross section (in case of perfect homogenic metal structure) ?

grr i just saw that i missed the sentence! Yes. you`re right - Direct Current means constant non varying current. I am wondering what happens inside the cylinder - where do electrons pass - all over the cross section or just at the surface. For the example the two points of current are the...

hi there! I have a bit stupid question: Imagine a solid metal cylinder. We put a . Explain to me please the exact model of the direct current electric flux of the particles. Is there a "skin effect" when a direct current is in action ?
