K The inner and outer conductors of a coaxial cable have radil of 0.5 cm and 1 cm, respectively. The conductors are made of copper with E,= 1, 1 = 1, and a = 5.8x107 S/m, and the outer conductor is 0.5 mm thick. At 10 MHz, determine the ac resistance per unit length of the cable.

A transmission-line cable, of length 3 km, consists of 19 strands of identical copper conductors, each 1.5 mm in diameter. Because of the twist of the strands, the actual length of each conductor is increased by 5%. Determine the resistance of the cable, if the resistivity of copper is 1.72 µ2-cm at 20°C.
