# Description

According to the set parameters line (Ro, Lo, Go, Co), the frequency f, the length of the line l, complex values \u200b\u200bof voltage U2 and current I2 at the end of the line, the load impedance Zl is required:
1. Calculate the voltage U1 and current I1 at the beginning of the line, active P and S total power at the beginning and end of the line, as well as the efficiency of the line.
2. Assuming that the line was the line of lossless (Ro = Go = 0), and the load on the end of the line to become active and equal load module integrated in paragraph 1, to determine the voltage U1 and current I1 at the beginning of the line and the length of the electromagnetic wave λ .
3. For the lossless line (item 2) to construct a graph of the distribution of the current along the line voltage as a function of the coordinate y.
It is given by: f = 3000 Hz, l = 56,7 km, R0 = 20 Ohms / km, C0 = 6 • 10-9 F / km
L0 = 4,1 • 10-3 H / km, G0 = 1,25 • 10-6 S / km, U2 = 42,3 B, Zl = 423 ohms.
