The bifilar pancake coil at its resonant frequency

[synchro1]

Also let's use Conrad's numbers again to look at the series bifilar coil a different way:

34 microhenries, 49 picofarads of self-capacitance

Let's just say that a reasonable peak-to-peak voltage for the self-resonating coil is 400 volts.

So the capacitive energy is 0.98 microjoules.

Now, I am going to make an apples and oranges comparison here.  Let's assume the inductor is pulsed at a low duty cycle in some kind of pulse circuit such that the average power dissipation from the 10-ohm coil is low and not an issue, and the peak current through the coil is 400 milliamperes.

So the inductive energy is 2.72 mircojoules.

Well, in this apples and oranges comparison, the two energy levels are pretty comparable and it certainly doesn't look like a gnat sitting on the back of an elephant.  However, there is one caveat.  If the coil is functioning in some kind of pulse circuit the self-capacitance is not really there, there is no real self-resonance taking place.  In that context you have what looks like a gnat sitting on the back of an elephant.

Finally, one last kick at the napkin.

If the self-resonance is say 40 volts peak-to-peak, then the energy stored in the self-capacitance is 0.0098 microjoules.  And the energy in the coll at 400 milliamperes is 2.72 microjoules.

In this apples and oranges comparison the inductive energy is 277 times the capacitive energy.  So more like a big racoon on the back on an elephant than a gnat on the back of an elephant.

Note how everything is in microjoules territory?  Here is an experiment for the "daring" - and it is an exercise in number crunching.  Find the right capacitance value for 10 microjoules of energy to charge the capacitor up to 10 volts.  Then touch the two terminals of the capacitor to your tongue and see what 10 microjoules feels like.  I am not even sure you will be able to feel the discharge.

What purpose does the series bifilar pancake or regular series bifilar coil serve?  I have asked this question many times and never got an answer.

@Milehigh,

Here's your answer; If you believe the question I re-asked above is meaningless, how can anyone place any credibility in your chronic de-bunking of Tesla's serial bifilar pancake coil?

@Milehigh,

You obviously either don't know your basics, or you're a stinking fraud. Now, which one is it?

@Citfa

How do we know you're telling the truth? Anyone can say anything, like I was a Naval aviator who kidded about leading the "Blue Angels". I think you're a liar. You can't understand basic laws of electronics and magnetism. Knock it off. The ruse is up. Everyone can see how little you really know. I'll tell you what's boring is trying to teach you simple basics you perpetually deny.

Allen You better talk to your lawyer before you call someone a liar on a public forum again.  He can explain what the consequences of your actions could be.  Defamation of character for no reason is punishable by our legal system.  I could easily own all you have if i desired to pursue your false claims against me.  You need to retract that statement with a public apology immediately.

My request has been sent to have Allen Burgess AKA Synchro1 permanently banned from this forum.  He has done nothing but cause trouble ever since he was allowed again to start posting.  He obviously has only one goal and that is to cause as much disruption of this forum as possible.  We certainly have better things to do than provide entertainment for a nine year old bully.

@Citfa,

Sue me you prevaricating "Crackpot"! Wait until you see my counter complaint for frivolous litigation. First you stated you studied electronics for 50 years, then you admitted all you did was sweep floors in a machine shop for 30.
