Inductance of a Transmission Line The inductance per meter of a single-phase two-wire transmission line is given by the equation: +In where L is the inductance in henrys per meter of line, 0 4 10-( H/m is the permeability of free space, D is the distance between the two conductors, and r is the radius of each conductor. Write a function that calculates the total inductance of a transmission line as a function of its length in kilometers, the spacing between the two conductors, and the diameter of each conductor. Use this function to cal- culate the inductance of a 100 km transmission line with conductors of radius r - 2 cm and distance D 1.5 m
