% Define parameters
d = 0.5; % Distance between conductors (in meters)
r = 0.02; % Radius of each conductor (in meters)
L = 1; % Length of the transmission line (in meters)
e0 = 8.854e-12; % Permittivity of free space (F/m)
u0 = 4*pi*1e-7; % Permeability of free space (H/m)
% Calculate resistance
R = 2 * pi * r * 0.0174 / (4 * pi * 1e-7);
% Calculate inductance
GMD = (d/2) * ((d/2) + sqrt(2*(r^2)));
L = (u0 / (pi)) * log(GMD/r);
% Calculate capacitance
C = (pi * e0) / (log(GMD/r));
% Display results
fprintf('Resistance: %.4f ohms\n', R);
fprintf('Inductance: %.4f H/m\n', L);
fprintf('Capacitance: %.4e F/m\n', C);

This script calculates the resistance (R), inductance (L), and capacitance (C) of a double-circuit transmission line based on the given parameters such as distance between conductors (d), radius of each conductor (r), and length of the transmission line (L).
