if you use larger, or more capacitors in parallel, do you also have to widen the distance or increase the surface area of the spark gap? in order to get the proper resonance?

In general...to maximize the the Tesla coil; the Primary/Secondary windings and coil diameters, Transformer output, Capacitor/Capacitors all have to balance?

I'm a 2nd yr Electrician apprentice..but my interest in electricity goes way beyond pulling BX and splicing conductors. Any advice is appreciated.

@ElectricalRevolution Go to thegeekgroup. o r g and get in the forums. :) We're happy to help.

totally a great video on resonance ...!! it was a innovative way of explaining it \m/

i wish you could make a video explaining how the entire tesla coil works

waiting for it!!

cheer and keep up the good work! (:

@raghul2hacker Do a youtube search for "Gemini Demo Video - Large Bipolar Tesla Coil"

It would be interesting to hear more about the properties of the plasma in the spark gap and oscillations while it is conducting. And while the plasma is conducting the capacitor will not charge so there will be a delay before it can do so again. What would these times typically be?

That's a whole video on it's own, and certainly not a beginner-level one. I'd be happy to get out some scopes and HV probes and do a video on that in the future though.

On the secondary coil, the wire-length has something to do with the resonance - some say that making a coil which uses exactly one quarter-wavelength of wire for the intended frequency will give maximum performance, though many say "B.S" to that...myself included.

Best lesson on resonance and tesla coil operation!!!

[Things0Burn]

Thank you for the great lesson on Resonance!

[Migueldeservantes]

Really really love the way that you explain it! great work! I hope you don't stop your tutorials!

[dacotacomodor]

well your way of teaching is very nice .and I like it

[gregca1234]

Very good explanation :)

[conspiracyco]

Some nice explanations. I would like to point out that Tesla says the transformer (magnifier) is not transverse nor electromagnetic. Tesla used oscillating current and rejected Einstein mass energy equivalence.

Teslas patent also features a third coil. This is important, I feel, due to the complex dimensionality of magneto dielectric mechanics in resonating oscillating systems such as this. . (The dimensionality of the devices wave output interaction, without the third coil wildly differs) :)

I have a secondary that is 8 inches wide by 45 inches tall with a 12,000 volt 30 ma transformer. Im looking to get about 8 foot spark when tuned right. Do u think that will be possible? Or do i need to get a more powerful transformer?

more, please.
