Cecil, the set of statements above is not true in the general case.


Owen, I told you a couple of days ago that I am talking
about average values during steady-state. If me talking
about average values during steady-state gets your
panties all bunched up, I profusely apologize.


if by 'changing' you mean 'changing with displacement or position', to
make these statements true, you must be talking about lossless or
distionless lines. If your entire discussion is premised on this, then
can your methods / formulas solve practical lossy line problems?

Nothing seems complete and self explanatory... so still, I am left
confused.
