... don't go man..

How pragmatic. as usual.

So how do you turn 2 coils into a capacitor that has NEAR no inductance. Remember ALL capacitors have inductance.

Now can you see how to turn a bifilar coil into a capacitor? and I'm not going to fall into your games.

If you get to doing that then place the other capacitor in series. :P

I will not post anymore here, after nearly 20yrs a member

Peter please remove me from the forum.

Adios.

hey mike

years ago playing with bifi coils, i had a thought on how the coil would act if it already had a charge on it, then shorting the other end. but didnt think to have that cap at the other end.  i tried diodes.  have to look back and see what i was doing and seeing then on that.


anyway im interested.   gotta get some things done tonight, already late, so ill get back tomorrow

Its not that hard




Wind a bifilar air coil, 1", 28mm dia with a twin wire, such as speaker cable, 12" long or 300mm.

Place a small compass next to the side of the coil.

Connect the coil as a capacitor only connect in series with a 20uF non polarised cap, speaker cross over cap is good.

Charge with 300v DC or so and watch the compass when charging.

Short through a 10 ohm 5w resistor and repeat.

Using two N mosfets such as IRF840 along with a flip flop or johnson counter clocked at say 10kHz should do the trick. You can change the frequency as needed.

You should see the needle deflection or (spin depending of the frequency), that is the emergent magnetic field between the plates ( turns of the coil )which only happens when charging.

Not complicated, you just have to think about it!

Why ?  Is it because F6 has a different opinion from yours?
Settle it by an experiment - not emotions.

Contrary to what is written, the coils you showed us are inductive.
Since the number of turns is odd, the magnetic field of one turn is not cancelled out.
You need to add or remove one turn.

What's not hard?
Providing images of coils is not difficult, and we could present dozens of others corresponding to Centralflow's text.
Not only do we not know exactly what type of coil he's talking about, but your images lack answers to key questions.

“Connect the coil as a capacitor only": meaningless sentence
How is the 20 µF capacitor or the switch connected?
“Charge with 300v DC": charge what? ‘the coil as a capacitor’ or the ‘20uF non polarised cap’?
“Short through a 10 ohm 5w resistor and repeat": short what? How? And repeat what?
“You can change the frequency as needed": what frequency? 0.1 Hz or 150 GHz? The order of magnitude isn't even indicated.

The only thing that's clear is that it's impossible to do, given the thousands of configurations you can imagine apart from this gibberish that makes no operational sense.
When you present an experiment, you have to do it precisely and respond to requests for clarification, otherwise it's really contempt for others. It's easy to see that the guy's not here to build anything, but to show off to the gullible, who will waste their time guessing and conjecturing before the grand master who pulls the mysterious strings and surely has a higher purpose than informing you. That's what we're doing now. The grand master has won, he has his cult.

the question i have is, are some capacitors made with the intention of having self inductance and some not? it would all be determined by what direction currents flow on each plate, or wire, as in bifilar coils.

like an audio crossover cap.  2 long foil plates with dielectric film between, rolled up in a cylinder package.  if both external leads, one connected to the end of each plate strip, are both connected at the same ends of the rolled strips, then id say that is a cap that doesnt have self inductance. if one lead of one plates were at the other end of the strip, then id say that there will be self inductance, because current flow through the plates would be in the same direction as in a single wire coil and its inductance.

Good point, maybe this is of some help:

from what i understand from Teslas pat on bifi, that the capacitance of the winding allows initial currents to flow negating the impedance of self induction and only the resistance would be in play.

ive had some ideas in the past on what we might be able to do with that, but most of them didnt pan out.

Why negating?   Why can't the two currents flow in parallel ?

...and only the resistance would be in play.
In such case the current should flow immediately upon application of the voltage, without delay.

This is correct, but only if the tape is not wound, or is wound like a solenoid, or more precisely with a very low inter-spire capacitance which presents a high impedance at the frequencies used.

If this is not the case, notably if the tape is wound like a flat coil (with an additional insulating strip for isolation between turns), then the inter-turn capacitance may have a low impedance at the frequencies used, and the signal will pass radially through the coil.

Finally, even the first case can give rise to artifacts at high frequencies. If, for example, the length of the inductance is of the order of 1/4 of the wavelength at the working frequency, then we'll have an overvoltage at the open end, and therefore a non-negligible current between plates due to the capacitive inter-turn effect at the end, and standing waves, even if the capacitance is very low.
A bifilar line is only a capacitor when frequencies are low, otherwise it's a transmission line, and we can no longer speak of a single capacitance, but of distributed capacitances, as well as distributed inductances, with interactions between them if they're wound so close. The operation is no longer at all the same.

like running parallel speakerr wire, current flows in the opposite direction, so inductive impedance is null between the 2 wires.  any inductance would be in the individual wires with multi strands.

supposedly yes.  say an ignition spark coil and we put 12v on the primary with the points.  when the points open, the condenser is across that open switch. the primary will oscillate with the condenser to about 300v
  so if we charge a cap to 300v and  connect that across the primary, we ill get as good of a 'multi' spark as with thhe points condenser.

so bifi, we could possibly charge up the bifi capacitance without opposition of inductance, time difference
read the Tesla pat on bifilar coils.

this charging of the bifi coil alone would be in my experience a quick discharge as soon as you put a meter on it.  but what mike had shown was a cap at the other end of the winding of which can help hod that charge for longer.  dunno

What's the point of charging a capacitor?
Because if we use a bifilar line and consider that its inductance is cancelled, we have a simple capacitor.

was just thinkin that if w can charge the bifi without interference of the inductance, then one winding would be depleted of electrons and the other packed with them then we short the open ends of the bifi.  would there be anything different than simply a charged cap applied to a normal winding?
