- The figure below is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a rubber layer, an outer conductor, and another rubber layer. In a particular application, the current in the inner conductor is I1 = 1.12 A out of the page and the current in the outer conductor is I2 = 3.04 A into the page.
