Sheet resistance of copper foil: Rule of Thumb #13 - EDN

Sheet resistance is applicable to two-dimensional systems in which thin films are considered two-dimensional entities. When the term sheet resistance is used, it is implied that the current is along the plane of the sheet, not perpendicular to it. In a regular three-dimensional conductor, the resistance can be written as WebJun 19, 2014 · We measure the thickness of copper foils by the weight per square foot.
