Acoaxial cable consists of alternating coaxial cylinders of conducting and insulating material. coaxial cabling is the primary type of non-fiber-optic cabling used for communications (i. e. cable tv) because of its superior ability to transmit electrical signal with minimum distortion. like all other kinds of cables, however, coaxial cables also have some self-inductance that has undesirable effects, such as producing some distortion and heating. consider a long coaxial cable made of two coaxial cylindrical conductors that carry equal currents i in opposite directions. the inner cylinder is a small solid conductor of radius a. the outer cylinder is a very thin walled conductor of radius b, electrically insulated from the inner conductor. the currents travel on the outer surface of each cylinder due to what is known as skin-effect.
