Joule Thief 101

Wattsup:

Before you can explain resonance you need to fully understand how amp ratings are produced for different wire AWG. They only give you amps but there is never any mention of volts so your wires are half identified which makes the amp tables more bugus then anything else. Totally useless in fact. So you guys find out how Standard EE derives amp ratings for copper wire and if you can do that and post it here and I will come back and explain to you what resonance is and what it means in your furthering of OU experiments.

Amp ratings for different wire sizes are simply based on making a reasonable estimate on how much resistive losses and corresponding heat generation the wire can sustain while at the same time remaining at a safe temperature in an environment that allows for a reasonable amount of air circulation.  Air circulation is a must.  Therefore often wire that is covered with insulation has a lower amp rating than the equivalent bare wire because the electrical insulation also acts as a thermal insulation.

There is absolutely no need to quote a voltage drop per meter for a given AWG wire gauge at the maximum rated current.  There is no information to be gained there.  You figure in most cases, like installing wiring in a building, that the voltage drop in the wire will not be significant.

So how about that, you can't answer the two questions either.  Your ferrite core discussion is bogus and doesn't answer either question.

My viewpoint is informed.

I answered your questions exactly. I can show you the mathematics of how this works,
it is basically the same math I have shown in most of the other examples.

I could go further, and break down the system into each individual component, the glass, the dimensional component of its shape and size,
as well as the vibratory translational effects of the liquid inside the glass, in direct relation to the frequencies input, along a graph.

But let us skip all that with which you will continue to argue, and move forward to what is exactly your point?
Do you intend to give some obscure and enlightening vision of "the mechanisms of vibration and how they make the glass resonate"?
Or some terms by which this frequency should be determined, other than what I already stated?

Do you intend to share your "informed viewpoint" ?
Or did you simply come here to tell us that 200 years of physics is wrong, then leave us in the dark?

Smoky2:

You did not even come close to answering the questions "exactly."  Do whatever you want to do to answer the two questions.  I asked two simple questions and requested two simple answers.  Do the math if you want, but math is not required.

I am hearing a lot of parroting-like talk, but nothing coming from the self that shows you or Brad have an innate understanding about resonance when it comes to a wine glass.  We are not talking about liquid being in the glass either, just an ordinary empty wine glass.  Forget about this business of rubbing your finger along the wineglass also, that is a distraction and not even in the question.

200 years of physics is definitely not wrong, but it appears that you and Brad can't take all of the Google searches and actually apply that knowledge and crystallize it down to answering two simple questions about a resonating wine glass.

So are you parrots or can you think for yourselves and demonstrate that you truly understand?

Here is how you determine the resonance freq. of a wineglass.  This method has been known since the 70's.

***Note: Only Memorex tape should be used for this.  No other tape could ever have any chance of working.***  Well, that is what the advertisers say anyway.
