you think current can stand still?
I will help :-)
Nope, is no current when no flow, is standing water. If flow then current,
my
dicksionary say so. Charge and credit cards can stay.
For those who think AC (and RF) current doesn't change directions every
1/2 cycle, here is a simple experiment, installed in a transmission line

The upper diode will rectify the current flowing toward the right.
The lower diode will rectify the current flowing toward the left.
Ideally, the meters will read the same.
For those who think current stands still at a standing wave current loop,
if one installs the above measuring equipment at a current maximum point
on a standing wave, it will read the same current on both meters and that
current will NOT be zero.

It's the charge flowing, Cecil. There wouldn't be any point in making
anything
out of the difference between charge and current flow except that you're
writing
about electromagnetic phenomena rather than network analysis where it's common
to write about current flow as if the current itself was was moving. As long as
you
continue to be blind to these kinds of subtle distinctions, your theories are
going
to remain little more than crackpot ranting. Yuri's in the same boat.
The other day, you made another mistake. You wrote that e^iwt represents
a standing wave. It doesn't. If you want to represent a standing wave
successfully
you have to have length included in the formula as in
2Acos(wt+ph/2)cos(kx+ph/2)
where k is 2Pi/Lambda and ph is the phase difference between two equal
amplitude
waves travelling in opposite directions, x representing length and A,
amplitude.
You're the victim of sloppy thinking and theorizing, Cecil. You think that
you can
use a strange combination of network theory and transmission line theory
definitions
and ideas to make sort of a poor man's electromagnetics, and that if you make a
large enough number of posts to this newsgroup your theory will be proved
right. If it were that easy, we could burn all the old electromagnetics
textbooks,
and smugly congratulate one another as we ate our marshmallows - roasted
over the bonfire - happy in the knowledge that we had finally rid the world of
vector calculus.
