Re: [TCML] magnifier efficiency




Bart,

My formula does not specify 120 bps. For small coils, 120 bps is needed to
obtain adequate efficiency, but for larger coils, the bps can often be
higher at 400 to 600 bps, etc. and still meet the formula's "predictions".

Large coils tend to be more efficient anyway in the sense that transformers
and maybe other components become more efficient when they're larger.
The lower frequencies that large coils usually run at may help also.

John

The formula assumes the efficiency of John's coils at the measured power, measured spark length, at 120 bps. It is an excellent prediction of potential spark length and has stood the test time. Many times, coilers will fall below this value (based on their lack of experience or lack of attempts to produce longer sparks with a given coil). Other times coilers produce longer than predicted sparks (it happens). 
 
The formula is empirical and not based on 100% efficiency or anything of the sort. 
 
Take care, 
Bart
