"WebThe transmission line has R, L and C components - impedance is the ratio of voltage phasor to current phasor. (2) It is 50 Ω because the ratio of inductance to capacitance per unit length produces that value. As R << j ω L and G → 0, these values can be ignored and so the expression reduces to L / C (frequency independent). " - Per unit impedance to ohms
