Slick and Cecil are talking about two different things.


I was a little sleepy when I wrote that. It didn't occur to me until
later that Slick can also use dQ/dt = 0 over a complete cycle to prove
that the average value of any AC current is zero, not just at a voltage
node. Hence the necessity for RMS values for AC.


That's not what i meant. I mean that with full reflections, there
will be nodes space 1/2 wavelengths apart that will have 0 RMS AC
current. These points will coincide with the absolute peak voltages
that occur on the line.



If Slick can tell a forward wave from a traveling wave by taking one and
only one current measurement at one point on a transmission line, and
knowing nothing else about the system, he is a better man than I.



More of your TRULY confusing terminology! It really helps you
cloud the
argument, doesn't it! Unfortunately, if you don't understand someone,
it usually means they are full of sh**!

A forward wave is a traveling wave, traveling forward.

If you give me the Max RMS AC current, and the Min RMS current, i
can most certainly tell you what the SWR is.
