The region between the conductors is filled with a linear dielectric material that has a relative permittivity er (recall, ε = Er €0). A voltage V is applied to a length h of the cable, resulting in a free-charge of qf residing on the inner conductor and -9f residing on the outer conductor. Part a Determine the D, E, and P...
2. Leakage Resistance of a Coax Cable The leakage resistivity of a coax cable's insulation is measured as follows. A known potential difference V is applied across the two conductors in a length L of the cable; the leakage current I that flows between them (through the insulation) is measured; and the resistivity is calculated from the voltage and current. The inner conductor has radius a and the outer conductor has inner radius b. The insulator fills the space between...
