Magnet Myths and Misconceptions

[EMJunkie]

Milehigh Failed miserably at a Litmus test question to see if he knew what he was talking about.

The question:

Why is it that the Speed of Light is not the Constant used in Coax, and only 62%?

Then brilliance, he agrees with the question:

It's because the impedance of the medium (inside the coax) is not the same as the impedance of free space.

I re-defined the question:

But why, other copper cables are 89%

Then a display of Ignorance and more Assumptions:

Copper cables are not coaxial cables.  Every setup will have it's characteristic impedance and the formula for the speed is something like the square root of the permittivity divided by the permeability.   That's probably wrong but it is in the ballpark.  I would have to go look it up but I am not going to bother.  It's all part of transmission line theory.

So I give some rope:

Ok, so here you prove my point again. Look we cant all know everything all the time. I am not going to nail you to the wall on this! Because really I don't care if you don't know the real reason why.

Still, your demand is a ridiculous one and proves nothing! It is not constructive and helps no-one!

Then MarkE come in and saves MileHigh's ass:

In a lossless transmission line the propagation velocity is:  c/(uR*eR)^0.5.  Most of the time in cables and etch inside printed wiring boards, uR is close to 1.0 and it is the eR that sets the velocity.  Typical printed circuit boards have eR values of 4-5 so the velocity is half or less of c inside the board.  The speed actually varies depending on how much of the fiberglass is glass and how much is resin.  At the ferocious data rates that we have today that can be a big problem because how traces line up with the glass bundles changes their timing.  In a coaxial cable that uses very low density PTFE foam the average eR is only about  1.5 and the velocity is about 0.8 c.  Higher density of PTFE increases the eR and further reduces the propagation velocity.  Traces that run on the top side of the circuit board send some of the energy through air above the trace and other energy through the board material underneath the trace.  These components run at different speeds and that distorts the signals.  But what can really drive fast signals batty is the protective nickel plating that is often applied between outside traces and gold top finish.  Nickel has a high uR.

I give MarkE the answer:

Ok, not bad MarkE. We can markE this as an answer because its close enough to what I was looking for.

See My point MileHigh!

So my point here is, these three people are playing tag team games with others here. Games that only an organised bunch of oil Company Trolls would have the tendency to play! These people are dangerous, lunatics!

Good at distorting truth, common-sense, direction and thoughts of others that do not stand up to these morons!

Truth will prevail and these idiots will be seen to be the morons they are!

Only Clown in the Room is MarkE, with his jester and best friend MileHigh, with the friendly little kitten NoBull

Seriously, you are idiots!

Oil Company Troll Idiots!

This is really sad.  Who do you hope to impress with such childish antics?

That's more sad behavior.  Truly, who do you think posts like that favorably impress?

You MarkE, like MileHogh, NoBull, TinselKoala display nothing but juvenile behaviour!

Don't like truth MarkE? Cant handle the Truth?
