4.13 A single-phase overhead transmission line consists of two solid alumi- num conductors having a radius of 3 cm with a spacing 3.5 m between centers. (a) Determine the total line inductance in mH/m. (b) Given the operating frequency to be 60 Hz, find the total inductive reactance of the line in /km and in /mi. (c) If the spacing is doubled to 7 m, how does the reactance change?
