Resonance Vs Mass 

I will start by my explanation with my usual guitar string analogy , if you tuned all the strings to the same note , by picking a string you will induce vibration in all the strings since they are tuned the same , on some strings the vibration will be barely noticeable but the string with a mass closer to the one of the picked string will vibrate more , ideally if you put two exact same mass string will vibrate just the same .


Ok , now what dose that show !

It tell us any mass coil will work together , but some will have a better power transfer ratio , saving on the losses .

So getting a better voltage and power transfer to the secondary , it needs to be mass tuned .

tuning all the strings is like putting caps to get circuit resonance , but with mass to mass , since its the same material and mass the freq is not a issue for power transfer .


@Jeanna

Try something for me , try a toroid directly on the EB , 2 coil on the toroid , make a small and large coil , then connect one coil on the EB, check the the other coil , then try the other way around .

Even though you have been ignoring me, here is the help you need to light your JT with the EB.

Don't feel singled out jesus, she's been ignoring me too.

I think she's spending all her time with some guy on the earth battery thread.

Well...at least we have each other huh...they say misery loves company, so maybe we should just enjoy our freedom from fickle women.

*goes off to ponder life*

Seriously though, she just probably missed your post.

Ignoring?

My apologies, jesus and cap, ... I did miss 2 of them?

Jesus, I did try the diode on the cap yesterday, and I even hooked it up 2 ways and it didn't start the jt.

with the neg band of the diode facing the pos side of the cap.
What if I put 2 caps together in series? Would that do it with the diode?

Thanks for the help.
