Title: I need answers, can't find a straight one anywhere, Tesla coil
Post by: clone477 on December 14, 2009, 07:23:13 PM
Hey Guys,
I searched high and low on google for an answer to this question but can't find anything that will explain. 

Is the secondary of a tesla coil always at 1/4 wave lenght IF it is properly tuned and in resonance with the primary??  To rephrase this, at 1/4 wave resonance the very top of the TC secondary will have the most voltage, while the bottom of the secondary should have 0volts, do I have to calculate a certain amount of wire for the secondary, or some other procedure to ensure 1/4 wave resonance??

I just want to make sure that when I build(this will be my 2nd TC), that I do have exactly 1/4 wave.  Thanks for helping a novice.  Fern

and this site - http://www.coe.ufrj.br - have done lot of work on Tesla resonance, and now no more in internet !!!!!

Well, you could speculate:

That a coil tuned for 1/4 resonance, may infact contain enough wire length for full wave length, ... the circumference of the loop will be proportional.

Therefore, if you wanted X number of turns, then you would simply take the full wave length into account, the diameter of the coil would be dependent on how many turns you want.

This is a purely proportional perspective, it may not in fact make any sense what so ever.

hi clone

i'm new here (just joined today  ;D) and i've had the same problem finding "original" tesla plans cuz i'm planning to build one early next year.

this site is one of the best i've found , hope it helps  http://www.richieburnett.co.uk/tesla.shtml

good luck ;D
