Question

Coaxial cables are often used to connect electrical devices, such as your video system, and in receiving signals in television cable systems. Model a long coaxial cable as a thin, cylindrical conducting shell of radius b concentric with a solid cylinder of radius a as shown. The conductors carry the same current i in opposite directions. Calculate the inductance L of a length of this cable.
