Exercise 3

The radii of the inner and outer conductors of a coaxial cable are a and b respectively and the medium in-between has a conductivity . Find the leakage resistance between the conductors per unit length by first assuming a leakage current I from the inner It the outer conductor, then determining J, E, V 0 , and R 1 = V 0 /I Check your result with Eq. (4-39).
