Because it should be obvious to anyone who knows enough to ask the
question.
Nevertheless, I assume the questioner is sincere so here is a simple
answer. It`s in Terman if you want more details.
Zo = sq rt Z/Y
Z = R + j omega L = line series impedance per unit length, ohms.
Y = G + j omega C = line shunt admittance per unit length, ohms.
For r-f in good lines, this reduces to:
Zo = sq rt L/C
For d-c, this reduces to:
Zo = sq rt R/G
Obviously line immpedance at d-c is likely quite different from line
impedance at r-f.
