A transmission line circuit is connected to a constant curre

A transmission line circuit is connected to a constant current source with l_0 at t=0 as shown below. The length of the line is L and the velocity of wave propagation on the line is v. Sketch the voltage on the line, V (z), for t = 1.5 v/L. Sketch the current on the line, l(z), for t = 3.5 v/L. Sketch the voltage on the line, V (z), for t = infinity. Make sure you express the magnitude of waves in terms of l_0.

Solution

Vz= Io(RL + Ro)

= 120*Io *1.5v/L
