3. Coaxial cable is used in applications requiring the propagation of high-frequency signal. Such cable consists
of a solid conducting cylinder as the inner conductor and a solid conducting cylindrical shell as the outer
conductor. A dielectric fills the region between these conductors.
Consider the RG-59/U coaxial cable that is commonly used to connect a television/internet equipment. It
has an inner conductor with a diameter of 0.584 mm, dielectric filler with a dielectric constant of K = 1.20,
and an outer conductor with an inner diameter of 3.7084 mm.
Assuming that these conductors are very long, calculate the capacitance per metre of the RG-59/U coaxial
cable. Include a derivation of an equation for the capacitance per unit length of the coaxial cable and then
use this equation to calculate your answer. (As discussed in class, assign a charge +Q and voltage V to the
inner conductor and a charge -Q and 0 V to the outer conductor, solve for the voltage V, and then compute
the…
The ratio of the inner conductor perimeter to the outer conductor perimeter of a coaxial cable is 0.4993 and how many structure capacitance pF/m is the insulated coaxial line?

7.3 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 E,= 1, .= 1, and a = 5.8-107 S/m, and the outer
conductor is 0.5 mm thick. At 10 MHz, determine the ac resistance per unit length of the cable.
