The point....what is it with you and points....there is no point.......you are being informed of my position, you are being informed of the existence of a solution not the demonstration of said solution....

That is so weak-ass and fake-ass, chances are you've got nothing.

The model is a self-resonating bifilar coil with a ground reference on one terminal and the other terminal swinging back and forth between +200 and -200 volts.

hmmm. In my experience I dont think you will get 400v in the cap if there is only an input swing of 200v this way and 200v that way. Thats like saying a 120vac line will charge a cap to 240v through a bridge rectifier.  And even in an lc, if you have an input of 200vac, 200v this way and 200 v that way, for the cap of the lc to reach 400v would kinda suggest that the lc is ringing at twice the voltage of the input. Ac is only 1 half cycle 'of directional' currents at a time, and the ac voltage rating is that of just a half cycle, whether it is rms or peak value.. Otherwise you seem to be saying that our AC home outlets are a 60v swing this way and a 60v swing that way and thats how we get 120v.  ???

I am in total agreement on the fact that the field collapse generates a current in the same direction of the input that built it. Could someone misinterpret a scope shot, seeing the voltage differential change at the time of input connect then disconnect as a current reversal? Maybe thats the bungle here?

@Mags,

Pulse by Reed switch, a "Positive Current" DC pulse enters the coil and is stored in a magnetic field. The Reed contacts separate, and a "Negative Current" DC pulse exits the coil in the same direction as the "Positive Pulse" was traveling. Wiring a reverse biased LED between the coil electrodes will produce a flickering LED from the "Negative Current" DC pulse.

sigh......

and they call you an authority.....

That's just another non sequitur.  Apparently you have nothing with respect to the question posed to make you think.

The watt-hour is NOT A MEASURE OF POWER. And there is no difference between the current leaving the coil in the same direction when power is interrupted, and the current leaving the coil when the power is on, except that the current when power is on may be steady-state, and the current when power is interrupted is decreasing. Your "negative current" is a misnomer.

@Tinselkoala,

Here's the definition of "Watt Hour": A measure of electrical energy equivalent to a power consumption of one watt for one hour.

Why do you keep trying to confuse people?

"Negative Current" is not a misnomer, it's a measure of positive current with reversed polarity. Everyone can understand how I use it in my explanation to Mags above in comment #870.

The terms flyback, reverse emf, counter emf are largely misinterpreted.  Flyback is a term that comes from the workings of a cathode ray tube, either a tv or an oscilloscope in which a particular function of the circuit that directs the electron beam to 'fly back' very fast to the left side of the screen after completing a slower visible trace from left to right and repeat. Counter emf and reverse emf should be referring to what happens in self induction of an inductor, where the field generated by the input induces an opposition to the input, thus the delay in getting to max current once the input is applied. I was stuck on that for a long time till about 6 or 7 years ago. i freaked out. lol But all of those terms might seem to suggest that the field collapse causes one or all of these functions, but none of them actually apply.

@Mags,

So what's your take on "Negative Current" imaginary or real?

Magluvin, the above is a pure gratuitous BS posting and you damn well know it.  I never said anything about charging a cap to 400 volts.  And then you do some nonsensical rambling in an attempt to "prove" me wrong.

You are falling into your serious character flaw trap like a fly stuck on flypaper yet again.  That is just a pure BS posting where in your mind you are going to try to pick apart every posting I make and find a flaw in it.  Well, you just exposed your serious character flaw with a nonsensical BS posting.

Get your act together right now and act like a decent self-respecting human being instead of some creep that is going to make posting after posting with some ridiculous negative spin about me like some psycho stalker.

Do you remember teaming up with Synchro1 for about one full year and harassing me and insulting me day in and day out without end?  Your behaviour was the WORST behaviour on a forum that I have ever seen from anyone in my life.  And you aren't going to start again with examples like that completely nonsensical posting shown above.

Get your act together.  You are not going to stalk me on this thread.

@Tinselkoala,

This is a quote from you:

"The watt-hour is NOT A MEASURE OF POWER".

Do think posting this kind of rubbish makes you look smart?

6 volts at 1 amp for 10 minutes equals a watt hour. Got it?

@Milehigh,

How the hell can you pretend there's any way you can help evostars with your seven year history compulsive, psychpathic bigotry towards Tesla's serial bifilar coil. You couldn't even solve a basic inductance problem any High School sophomore could handle with little difficulty.

There, I fixed that for you.

@Tinselkoala,

Here's the definition of "Watt Hour": A measure of electrical energy equivalent to a power consumption of one watt for one hour.

Why do you keep trying to confuse people?

"Negative Current" is not a misnomer, it's a measure of positive current with reversed polarity. Everyone can understand how I use it in my explanation to Mags above in comment #870.

Do you actually understand the difference between POWER and ENERGY? Apparently you do not. Here's what you said:

1 watt hour of power generates 1 Tesla of magnetic force in a coil of 1 Henry of inductance. How come no one could answer this question?



The Watt-Hour is NOT A MEASURE OF POWER..... can't you get that through your head? Now that you have googled the definition THAT AGREES WITH ME....


And "Everyone" by now understands that you are a blowhard troll who would rather use his own (incorrect) definitions of common words instead of admitting he is wrong.

The Watt-hour is NOT A MEASURE OF POWER.  It is a measure of ENERGY.  Look it up again, since you apparently cannot even remember your own googling.

You are the one who is confused, as everyone reading here can see for themselves in your own words.

6 volts x 1 amp = 6 watts. 6 watts = 6 Joules of ENERGY per second. 6 Joules of ENERGY per second x 60 seconds/minute x 10 minutes = 3600 JOULES of ENERGY. 1 Watt-hour = 3600 JOULES of ENERGY,  so at least you got that right.  ENERGY, not POWER.

GOT IT?
