Building a Tesla Coil - Part 2 (A)

This is the second part of my video describing how to build a typical spark-gap type Tesla Coil. But this was too long, so I had to split it into two parts. Sorry! Be sure you watch Part B after this.

You mentioned that capacitive reactance and inductive reactance can be tuned by changing the number or turns in primary winding. What about the resonance in secondary winding? Do you need to tuned the secondary winding to gets XL(sec) = XC(sec)?  If yes, how to tune secondary winding? Thank you.

When you change the number of turns in the primary winding, you change the inductance, which in turn changes the inductive reactance. Some people also use a movable tap on the primary winding. However, you don't really have any easy way of changing the inductive reactance in the secondary circuit without having to make a new winding. You can change the capacitive reactance by using different toploads though.

And I have to admit, I'm still not completely sure how the voltage rises with resonance. I can kind of understand how a Tesla Coil generates high frequency, but I'm still not sure exactly how it increases the voltage.

Will changing the size of the toroid/capacitance on the secondary affect the tesla coil's function if building a solid state tesla coil? I'm also curious how leaving the ends of the secondary windings outside affects a SSTC since I've seen a lot of people have them point straight up out of the center of the top.

@carnotricecooker

Since it's a resonant circuit, I would think that changing capacitance or inductance would still affect it regardless of whether it's a spark gap coil or solid state.

And pointing the ends of the winding through the top is a bad idea because you can get corona inside the winding. I guess you might be able get away with it with solid state because usually the voltage is lower than what you get with a spark gap coil.

what is a ignition coil n-point or mid point?

[ct92404]

@cyrusrom

an ignition coil has only one secondary winding, and it's end-point grounded to the negative terminal.

@ct92404 The discharging of an inductor implies that it will maintain the current applied in it, thus rising voltage.

Interesting and well described. However what we need to know in order to understand how forces of nature are originated by the charge field is the law behind these. It would be great if you can experimentally reproduce the principles presented in: scribd: 45747120/Unified-Field-Explain­ed-9

Ok have a few questions if your up for answering. I have a 10kv midpoint furnace transformer. Would this workk instead of a neon transformer? Seems to be kinda hard to find a n-point transformer cheap. Second i have 2 ,18kv capacitos with a capacitance value of .0004 mf. would it be better to have them in parrell or series? Last how do you figure out you spark gap for your safty gap?

im to dumb to understand what this means... but i thnk its cool!

Wow. Nicely done. You should work for NASA - oh wait...

Well maybe you can work for GM/GE - oh wait...

How about LLNL - oh, wait...

Hmmm... Maybe you should continue development on your ownas an alternative to the Chevy Volt.

Oh, wait...
