Hello, everybody,
I was reading, recently, about a coil that was using 34AWG wire for the secondary and was ran at low power levels (150VA) without any racing sparks or any other forms of damage. I was wondering if it would be possible to use a secondary wound with 40AWG wire, or if this would just be a ridiculous idea.
I understand that it would be extremely difficult to wind a secondary with this thin of wire, and that the chances of the wire breaking are large, but I'm looking for more of a proof than an efficient coil. The form I would be using is a cardboard one with a spray-coat of polyurethane, 1.5" diameter by 7" height.
Since TeslaMap didn't have a 40AWG option for secondary wire, I had to do my own calculations -
Using a wire diameter of 3.14 mils to represent the diameter of the 40AWG wire, I divided '1' by '3.14' and multiplied by one-thousand so that the number would be how many winds per inch, instead of winds per mil. I took that number and multiplied it by '7', the intended number of inches for the secondary's windings in length; I came to the answer of 2229.29 winds in seven inches, with a height:diameter of 1:4.66(etc.), which is acceptable for small coils.
Since the power supply I'm using is only 3KV at 15mA I have a primary capacitance of 20nF (.02µF). The input power is only 45VA, which isn't much energy, especially when the capacitor's output is only about .1 Joules (.09).
Anyways, I'm just wondering if you guys think it'll work, and I'm hoping to get a topic started.
