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.
To fill the table, you will need to apply specific formulas for each section. Let's go through them one by one:
1. Conductivity in Siemens per meter (σ): This is a measure of a material's ability to conduct electric current. To calculate it, you need the values of the resistivity (ρ) and the cross-sectional area (A). The formula to use is:
σ = 1 / ρ
2. Conductivity depending on w and E: This section requires you to fill in values based on the given equation:
σ = w / E
Here, σ represents the conductivity, w represents the conductance (which is the reciprocal of resistance), and E represents the electric field strength. Therefore, you need to know the values of w and E to calculate σ.
3. Material behavior: This section is not explicitly defined in the image you provided. However, material behavior often refers to whether a material is conductive, insulating, or semiconducting. You need to determine the appropriate label for each material based on its conductivity values in the previous sections. Conductive materials have high conductivity, while insulating materials have low conductivity.
To fill in the table accurately, you need to have additional information such as the given values of resistivity (ρ), conductance (w), and electric field strength (E) for each material. Without these specific values, it is not possible to provide exact information for each cell in the table.
