Joule Thief 101

Ha ha ha - busted.

Since you have never actually built a JT,
you can go to school.

http://www.learningaboutelectronics.com/Articles/Diode-resistance.php

combine the magnitude of the resistance, with the phase angle,
and you can observe the effects of adding the diode to the circuit.
(impedance)
once you learn this, we can move on to the concept of capacitance, within the diode.

maybe tomorrow I can teach you how a WIRE works....

Don't make me laugh Smoky2.  The term "internal resistance" is used for things like batteries, not diodes.  In common electronics terminology, you never say that diodes have an "internal resistance," you talk about their I-V transfer curves or absolute equivalent resistance at a given operating point or their differential resistance at a given operating point.

You have seen me post enough in this thread to have a reasonable grasp of my electronics knowledge level.  So posting the "instructional material" is just you making a fool of yourself, more pants pissing.

I'm not going to pretend to know what level your "electronics skills" are at,
as you seem to have a difficult time grasping simple basic concepts.
You have absolutely no hands on experience with this circuit,
you are both unqualified, and out of your field of expertise

the only reference point you have on this subject is other peoples work on the JT.
Yet you argue over "how it works", and don't even know what type of circuit this is.
or maybe you just get to high to even bother to read whats sat in front of you.

either way, if all you want to do is argue and laugh at things, wtf are you here for?

we already established 6 pages ago,
the effects of tiny changes in impedance, capacitance, and inductance can change the outcome.

at a given frequency, voltage and current curves:

a diode performs rather consistently.
If you take this diode and place it in that JT, or the other JT, at the same freq.
it will represent the same impedance.


I would tell you to:
Take the red and the green out of your desktop PC case, and compare them.
but I think we both know you are not going to follow me through such a simple lesson.

you would rather tell me that nothing matters and demand I demonstrate "how a diode works"
or some other unfounded protest against basic electronics theory.

the two images above pretty much say it all, the link was more of sarcasm....
I doubt you read more than the first sentence, if you even followed the link at all.

I have no intention of discussing the internal resistance, voltage levels, and current through the battery.
this can be considered a unique "constant" to a circuit. And may vary from battery to battery.
it is presumed that any testing will take place using the same battery (per rendition of the device).

We have very little control over the batteries internals (in most battery types).
So, for now, such discussion would just add unnecessary confusion.

AA, AAA, button cell?
EB, electrochemical, galvanic?
reverse fed through a neon bulb, powered by proximity to a leyden jar?
[I think I'll stop there, so as not to raise too many eyebrows]

Depending on which tune is playing the trons and the hoes might eye each other across the dance floor on opposite sides of the room like so many wallflowers.  Then the DJ puts on a new tune and the trons and the hoes race towards each other in the center of the dance floor in a frenzy and make contact and seemingly leave this plane of existence.

The DJ is really good, and as the Millenniums say these days, "He is dope."
