I've heard the equation described as polar, but does anyone know of any specific formulas describing E, the electric field? Are they different for different sheets? I've also heard that they would be independent of resistivity - at least on the scale that I'm interested in. Is there only one general equation for all sheets - or is it dependent on the material of the sheet? If so, is there an equation that includes the properties of the sheet - and not the actual type of material? Does the equation only involve the length and width of the sheet? At what depth does the depth of the sheet make a significant difference?

I've made some posts about different causes of resistance in sheets - and different causes of resistance in the specific type of sheet mentioned in this post - between two point electric contacts. Maybe I should clarify that the sheet could be as large as two feet by two feet - and is therefore much larger than any sheets that might be found in resistors - if this makes a difference. Some people have mentioned some equations, but I'd like to know of a formula for E that actually represents the shape of the field.
