The inner and outer conductors of a coaxial cable have radii of 0.5 cm and 1 cm, respectively. The conductors are made of copper with r = 1, μr = 1 and 5.8 x 107 S/m, and the outer conductor is 0.5 mm thick. At 10 MHz:
(a) Are the conductors thick enough to be considered infinitely thick so far as the flow of current through them is concerned?
(b) Determine the surface resistance Rs.
(c) Determine the a-c resistance per unit length of the cable.
