Webcase the total electric field would be the sum of the electric fields from the two cylinders, using superposition. In fact, this is a coaxial cable, the cable used to transmit TV signals. etc. A coaxial cable (the word means “same axis”) has a central copper wire, inside a hollow copper cylinder (see figure below). WebDec 14, 2024 · Since we want to determine the electric field between the cylinders it is necessary to find a surface that is everywhere perpendicular to it (i.e. a surface with a normal that is parallel to the electric field). The dot product in the above expression is non-zero in such a case. Figure 3 illustrates the surface that satisfies this requirement.
