less than the input voltage by 3 kV, because of the voltage drop in the line. In the

transient, the voltages and currents change stepwise, owing to the interaction of the

incident and reected waves. The amplitude of the rst voltage wave at the output

is bigger than the amplitude of the input wave, and the situation is opposite for the

currents. Under repeating of simulation with R = 190 Ω, it is seen that the amplitude

of the rst voltage wave at the output is less than the amplitude of the input wave. As

before, the interaction of the incident and reected waves can be seen.

Let us carry on simulation under ...
