Re: Racing Spark Prediction

Hi Dest,   (is that better?)

I believe both the primary and secondary have both frequencies in them. Its not a case where the secondary takes on one frequency and the primary takes on the other. If both frequencies are in the secondary and a "full" beat period occurs (and lets say there is no decay in this period of time) then the beat envelope could aggrevate the voltage gradient to cause a racing arc. That's the premise this discussion is based upon.

when two circuits are coupled, secondary gets _new_ resonance
frequency f2=fo/sqrt(1-k), so what problem do you see in beating?
i see none.
