I have to fill the following table, I know it should only be applying formulas, but I'm not sure which formulas should I apply in every section.

I would like to know which is the difference between the conductivity in Siemens per meter and the conductivity depending on w and E. I also have no idea of what should I input in the Material behaviour area.

Thank you very much.
