inductance of the line change if the diameter of each conductor were doubled? 2 Capacitance of a Transmission Line The capacitance per meter of a singlephase two-wire transmission line is given by the equation $$ C=\frac{\pi \varepsilon}{\ln \left(\frac{D-r}{r} ight)} $$ where $C$ is the capacitance in farads per meter of line, $\varepsilon_0=4 \pi \times 10^{-7} \mathrm{~F} / \mathrm{m}$ is the permittivity 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 capacitance 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 calculate the capacitance of a $100 \mathrm{~km}$ transmission line with conductors of radius $r=2 \mathrm{~cm}$ and distance $D=1.5 \mathrm{~m}$. What happens to the inductance and capacitance of a transmission line as the distance between the two conductors increases
