Joule Thief 101

then the real and the ideal coil as defined are virtually indistinguishable

Other than one not having any resistance,and there for dose not dissipate any power,to one that dose have resistance,and dose dissipate power.

I sure as hell understand the difference between a real inductor and an ideal inductor.

I dont think you can.
You just cannot grasp the difference a small amount of resistance to that of no resistance.
As you can see,one has a finite time constant,and one an infinite constant.
But i see now your test is determined by a time limit,and so you think all will be equal--the MH paradox

More complete and utter foolishness because your powers of conceptualization and application of knowledge are almost nil.

Hows them understandings on resonant systems coming along MH?
Have you learned what a J/FET is yet,and how it works?.

Here is what you don't understand:  When you look at the example which is over a period of three seconds, then the real and the ideal coil as defined are virtually indistinguishable.  You have to factor in time and you are blind to this fact.

Along with the fact that your ideal inductor has 4 volts across it for 3 seconds--as stated in your question--along with all your other voltage drops and reversing polarities.

Looking forward to your answer on a finite inductance value for an inductor with no resistance

This whole time you have clearly not understood what inductance is and that is the crux of the problem.  You have been bluffing your way through for years.

Hit the reset button and open an electronics book from page 1 and start reading.

I would think that some one that dose not know what a J/FET is,or dose not understand what DC is,or cant grasp the fact that there is a difference between an object vibrating at it's natural frequency to that object resonating,would be far better off hitting the books.

Yes, what is it now, 25 to 35 times you have stated this?

When this first came up I clearly told you that last time I discussed a JFET was 35 years ago sitting in an electronics class and I forgot the the definition.  But like a sleaze you are going to repeat that until you are blue in the face.

Let me make it clear to you:  You can pretend and make yourself believe that you are 'toying' with me all you want.  But at the end of the day you are still the poor schmuck that fell flat on your face with respect to inductors and exposed how clueless you truly are and how you will likely never be able to answer a very simple question about electronics that consists of a power source and a single lousy component.

You have to change your attitude and learn this stuff from scratch.

That makes 36 times now.  The whole arc of this discussion going back a few months now when I decided to treat you as a normal person has been an endless series of complete fiascos, crazy mistakes, and the most ridiculous obstinate refusals from you to accept new ideas or unlearn your crazy ideas so you could advance and accomplish some good things and make good progress.

You do not stand a chance of answering the easy question or the harder question and you bluffed and evaded the easy question when I told you to substitute a real coil for the "problem" ideal coil.  You can stew in your juices and pretend that you are doing electronics as long as you want, I don't care.

MH, Mags, tinman,

Why are you guys badgering each other like this?

All three of you know very well what an ideal voltage source is (and you know each other does as well), and mags/Brad, you know full well what MH means in his question and/or his posts when he says the voltage source varies.

To be clear, he does not mean that it varies from its set value over time, he means it is one value for time x, and another value for time y.

So please stop this pages and pages of nonsense, and get on with some productive discussions.
