Problem 6 (10 points) (Chap 3) (Learning objective: Coaxial line) An air-filled coaxial line exhibits a characteristic impedance of 90 2. It is desired to modify the cable to reduce the characteristic impedance to 62 2. Describe two different ways to accomplish this. One way should involve geometry, and the other way should involve ma- terial. You may assume the inner and outer conductors exhibit negligible resistance. Please be specific; give numbers.

3. A two conductor main A B, 500 m in length is fed from both ends at 250 volts. Loads of 50 A, 60 A, 40 A and 30 A are tapped at distance of 100 m, 250 m, 350 m and 400 m from end A respectively. If the X- section of conductor be 1 cm and specific resistance of the material of the conductor is 1-7 u 2 cm, determine the minimum consumer voltage.
A two wire DC distributor AB, 1000 meter long, is supplied from both ends, 240 V at A and 242 V at B. There is a concentrated load of 200 A at a distance of 400 meter from A and a uniformly load 1.0 A/m between the midpoint and end B. Determine (i) the current fed at points A and B (ii) the point of minimum potential and (iii) voltage and this point. Consider cable resistance as 0.005 ohm per 1000 meter each core.
