Some may not realize that E is an rms value. Keith early in the thread
was inserting instantaneous volts which can be an infinite range of
values as they may be taken at any point in a cycle for evaluation. I
agree with Cecil`s "tits on a boar hog" characterization of value in
transmission line problem utility.
