Joule Thief 101

Complete and Utter Rubbish!!!

Why is it that we measure the Phase difference from Voltage to Current in Transformers?

Because this value Changes depending on Load and Transformer Configuration.

I have already proven you wrong!

You are deliberately BSing the masses to save face!!!

You know for a FACT that I am right and you are wrong. But someone is PAYING you to LIE to everyone!!!

TK shame, shame on you!!!

Brad, as I've demonstrated in a video a few pages back, and as we know, the total phase shift that can be measured depends somewhat on the frequency of the oscillation, because different core materials respond differently and there will always be stray inductances and capacitances caused by wiring. SO I had to increase the frequency of my test setup to get the perfect relationship shown below.

I'm using the same setup as in my previous demonstrations, using the random ferrite-cored transformer, except that I am testing two conditions.

First, the transformer secondary open, just connected to the scope probe, so I am testing the _voltage_ across the secondary, unloaded. This produces the first scopeshot below: The 90 degree phase relationship between the applied primary current (i.e. the magnetic field) and the secondary's induced _voltage_. And as I've shown, this nice 90 degree relationship holds across a wide range of applied frequency. (30Hz, 1 kHz, and in the shot below, around 700 Hz.)

In the second scopeshot below I have attached a 1.0 ohm precision non-inductive resistor directly across the transformer's secondary, and then the probe across the resistor. So the resistor is acting both as a load, and its own CSR. Now the scope probe is measuring the _current_ as a voltage drop across this resistor.

As I said, I had to increase the frequency to make the _current_ phase shift look so accurately 180 degrees. If I perform this same comparison test at 30 Hz, I "only" get a total phase shift of about 140 degrees for the _current_, while the _voltage_ phase shift remains at 90 degrees-- as I showed earlier.

No, you have not proven anything except how ignorant and arrogant you are.
I am not wrong and I've given demonstration after demonstration of everything I've said and explained. All you've done is copy-paste and misinterpret.

You are deliberately BSing the masses to save face!!!

You are more than hilarious. I've refuted you time and time again, and ANYONE can repeat my demonstrations for themselves.... even YOU should be able to do it...
and can check my references re Faraday's Law and the algebra and calculus for themselves. The only BS here is coming from YOU.

YOU ARE WRONG, and you are lying, and NOBODY is paying me to do any of this _remedial basic education_.

Brad:

I am a "big gun" according to you, so what happened?  I can tell you what happened.  You were not given a continuously enabling environment by me, you were put on a level playing field and when you were wrong about something you were told you were wrong.  It is extremely upsetting for you to be told that you are wrong.  You can't admit that you are wrong when you are indeed wrong.  And I am not saying at all that you are wrong all the time, but like any person it does actually happen that you are wrong.

At that is enough to give you a good hard-core freak-out and make you completely compromise your integrity.  Now you will say anything and lie through your teeth repeatedly.  I am not perfect and I get things wrong and I admit that.  But you are lying about me repeatedly.  It's a very sad, very very unpleasant spectacle.  You have no shame whatsoever.

Your credibility is destroyed, poor Brad on a brain fry from hell.

English MH--English.

I am not having a brain fry at all MH--im having a --no more shit from MH time

Feel free to point out where i was wrong,and did not admit it.

What is sad is,seeing some one that use to be helpful, turn into some one that must be right,and when they find out they are wrong,they attack those that pointed out there mistake to them.
That is referring to you by the way.

Nope, I speak the truth but ever since your brain started to fry you have been shamelessly bullshitting like crazy

.

No resonant systems what so ever around an ICE--wrong
No resonance what so ever within the internals of an ICE--wrong
Your statement about using a J/FET makes no sense--wrong

Who is bullshitting ?.

Right, only one scope trace but no dots.  GOOD PRACTICE, Brad.  It shows a normal transformer action.  There you go.

If you are full bottles on transformer induction,why do you need dots ?.

GOOD PRACTICE:  Don't say two setups are the same when they aren't.  No bluff there, let it sink into your head.

Another lie,as i never said the two setups were the same,and you only had one setup when the question was first asked.
The nose grows long with this one MH.

Keep on lying like a drunk sailor.

Another lie,as i do not drink.
Please post these lies MH.

Then what the hell are you even doing that for?  More nonsense.

Already explained--twice,and it had nothing to do with you answering the question.

I do indeed have a little touch of dyslexia.  And you need to take some courses in remedial English and remedial English composition so that you can learn how to spell, learn how to use punctuation, and learn how to put a proper sentence together and learn how to compose a paragraph.

Then stop blaming your problems on me,and get them sorted.
If it dose not come up in red(indicating there is a spelling mistake),then i do not correct it. I am not here to win some sort of spelling bee MH.
Why are you the only one having a problem ?.

You are just shamelessly lying and there is nothing wrong with the sentence.

Yes there is.
TK gave an answer in the correct manor-yours is wrongly termed.

More shameless lying and you are off in dreamland with your incorrect belief that magnets can do useful work.  It represents both a hopeful belief on your part and a fundamental misunderstanding of how the world works.  Magnets are as dead as a door nail and are not a source of energy in any way, shape, or form.  I know that you refuse to believe this.

Babble on MH.
You say i do not know how the world works,but you are full bottles on a force that you have no idea as to what it is. Bookworms often make claims about things they do not understand.

There is nothing wrong with that sentence.  Then of course you have typed out hundreds of contorted brain twisters over the years that would make any fifth grade English teacher's jaw drop.  Go to English school.

Like i said,no one else has a problem--only you.
