what happens between a teslacoil the battery the incadescent bulb and the ground

[TeslaScientific]

This fight will never stop ,unless somebody show that Tesla coil can be used in 2 or 3 completely different modes of operation. That is the reason people cannot replicate Tesla findings. Confusion.
Would be VERY VERY IMPORTANT to scale down TeslaScientific Tesla coil and compare the results with RF version. I do believe this is not RF exactly like Tesla said.

It can be, but the question was how to explain the effect. So I said remove all the unnecessary components, and see what causes it. Instead of fiddling with the circuit and battery, that's not what the source of the effect is. It's the high frequency high potential AC output from the coil. Replace the circuit entirely, remove the battery, change everything, and the effect will remain, because the coil remains. So if it can be done without the circuit or the battery, then neither the circuit nor the battery have anything to do with the effect.

The coil I'm using is Tesla's Colorado Springs coil scaled down to the 160 metre amateur radio band, but it works the same with every coil.

It's a SINGLE wire single terminal transmission system. There is no "ground loop" or "closed circuits" through air gaps. It's exactly like the AT&T/Bell Labs video shows. The waves reflect/oscillate back and forth along the transmission line/structure, and that's why the bulb lights with one wire, not because of imaginary closed circuits. It's not necessary to form a closed circuit.

That is not correct--there is always a path for the current to follow-or flow through.

In this case,it is via capacitive coupling,as shown in all your pictures you posted,where you are one end/plate of that capacitor.

Try lighting your incandescent bulb's without touching them,or having a can(as a cap plate) attached to one end of the bulb--you will see that it will either not light at all,or it will be extremely dull,where the bulb casing itself is acting as a small capacitor plate.

At high frequencies,even the smallest value of capacitance can deliver high amounts of current-even when that path is through the air.

Your incandescent bulb's(and i suspect the same with TKs setup),are being lit due to capacitive coupling,which completes the path for current to flow,and where the air around you is the dielectric between the capacitor plates(you and the circuit).

What is that magic "capacitive coupling" ? People are trying to explain everything based on this concept, but it is only related to RF coupling.


What if the bulb is on the long line connected to one of the terminals of the dual Tesla coil secondary with the second terminal connected to the proper capacitor plate, and bulb is connected then to the metallic plate and is brightly lit ? That was described in one of Tesla;s lectures.

RF-meaning high frequency.
As i stated,a very small value capacitance can deliver high currents at high frequencies.

The answer is very simple--can you light an incandescent bulb with only one of it's terminals connected to one half of the source?

Every time you see an incandescent bulb being lit,it always has a capacitive coupler plate connected to one terminal of the bulb,and the other terminal of the bulb is connected to one part of the circuit.

Try and light an incandescent bulb as pictured below,where there is no capacitive path for current to flow.

forest,read this,and you will understand what i am talking about

Quote:  At much higher frequencies, however, it is possible for the return circuit (which would normally be connected through a second wire) to utilize the self- and parasitic capacitance of a large conductive object, perhaps the housing of the load itself. Although the self-capacitance of even large objects is rather small in ordinary terms, as Tesla himself appreciated it is possible to resonate that capacitance using a sufficiently large inductor (depending on the frequency used), in which case the large reactance of that capacitance is cancelled out. This allows a large current to flow (and a large power to be supplied to the load) without requiring an extremely high voltage source.
