A coaxial cable consists of a solid center conducting wire and an outer coaxial cylindrical conductor. The space between the conductors and the outer insulation are made of a good insulating
material e.g. neoprene. The figure below shows a cross section of such a cable. The current in the center wire is 2.16 A out of the page and the current in the outer conductor is 3.91 A into the
page. If the distance a is 2.00 mm, determine the following.
&I,

This is the end view of a coaxial cable. The central solid
wire carries a current I sub one perpendicular to and out of
the page and the coaxial cylinder has a finite thickness and
carries a current I sub two perpendicular to and into the
page. The coaxial arrangement is surrounded by some
material. There are two points labeled P sub one and P
sub two on a horizontal line to the right and from the
center of the solid wire. The point P sub one is between
the central solid wire and the coaxial cylinder and is a
distance labeled a from the center. The outer radius of the
coaxial cylinder is labeled two a and the point P sub two is
outside the coaxial cylinder and the surrounding material
and is at a distance labeled three a from the center.
