Joule Thief 101

[EMJunkie]

You show a transformer and you are too dense and too lazy to use the dot convention.  You have been reminded of that several times before.

What a pathetic Excuse to avoid the questions asked!!!

Shame!!!

Yes, I was unaware that there are ways to take advantage of resonance in a cylinder during combustion, and also for getting better air flow into and out of the cylinders.  I never claimed to be an expert in engines.  So what are you going to do?  Jump up and down in a victory jig?  Have your jig and eat it too.

What i am going to do-and what i have done,is show people the truth,and not believe everything they are told. You just happened to be the example-a position you placed your self in.

You also continue with your insult's,and claim that i am always wrong-even though you admit your self that it is you that has been wrong so far on this thread in regards to resonant system's,and how those resonant systems increase the efficiency of the systems they are working in.

For many years now,you thought of your self as being above me--better than me,and yet here in this thread,we see that that is not the case. But still you continue to belittle me,and insult me as you see fit,and all based around the fact that i know some things you do not in the area you consider yourself to be so great at.

I have asked you and minnie twice now to answer a simple question,in an area yourself and minnie think i need to work on,and learn a bit more toward--that being induction.
But so far,neither of you have stepped up to the plate,and answered this simple question about induction--which scope trace is correct for the circuit schematic.

There is only one of two reason's neither of you will answer-
1-you do not know the correct answer yourselves-a simple question on induction-
2-you do not want to agree with what EMJ says about Lenz's law in relation to faraday's law of induction-simply because EMJ is saying it. This is just the cowards way out ,if that is the case.

So here it is once again-for you and minnie--the two that claim i need to brush up on my understanding of induction.
Is the first scope shot with the associated schematic correct?
Or is the second scope shot with associated scope shot correct.

1 is correct,one is not--which is it?.

I will add a little something for you to think about.
Both scope shot's are from the same circuit.
1 scope shot is the result of a PM (that can do no useful work )placed next to the transformer,and oscillating at the resonant frequency of that transformer,but where the field alignment dose not change.

In this thread you are being told the truth by me, no kid gloves and no spoon feeding.  If you are right then you are right and if you are wrong then you are wrong.  It's a shocking dose of reality for you.  Notice that is "dose" and not "does."

Am I perfect?  The answer is no.  Have I turned into a borderline psycho person because of this thread?  The answer is no.  Have you turned into a borderline psycho person because of this thread?  The answer is yes.

Keep on repeating I am wrong until you are blue in the face and your brain sizzles and smoke starts rising.  Go for it.

WOW, are you secretly a Politician?

Lies and Aviodances seems to be your primary area of expertese!!!

Certianly Electronics/Magnetics is not!!!

and still none of the Questions have been answered!!!

Hey Brad,

Yes Sir, equal and opposite, but, there is a small catch here, reactive power can change the phase angle some! Which has nothing to do at all with Faradays Law or Lenz's Law.

This is Ping Pong Power, if an Ideal Inductor were considered, the power you put in, is the power you get out again. So properly interpreting your scope shots, you need to take into account the Phase angle on your Input.

If youre getting 90 Degrees, then the Power you put In, you get all that back out again. This is a Lossless Inductor!

To Calculate this, its: V * A * Cos(ϕ)

Where:
ϕ = Phase angle from Volts to Current, or sometimes Current to Volts.
V = Volts
A = Amps

What is cosine of 90 degrees, O Great Sykes? It is ZERO.

A little bit of reference material here: Transformer: primary side & secondary side current 180 degree out of phase

It is very standard knowledge in Electronics/Transformer Theory. I am super surprised TK got this so terribly wrong!

I have built a small App if you want to use it, it calculates the Params you put in. Need to know the Phase angle of Current to Voltage, if its Voltage leading.

Current is not voltage (EMF).  When a _Voltage_ is applied to an inductor, the _current_ takes some time to rise up to its final value. In Brad's schematic he is measuring _current_ through a resistor on one coil, and _voltage_ across the second coil.
