 How is the extremely high frequency of a tesla coil
 acheived by using an RSG?  
 
 
 considering 3600 RPM (just a GUESStimate) with a mark
 at every 15 degrees, you would only get 60hz :-/....
 to run a tesla coil isnt the frequency needed about
 300-500kHZ???
 
 thanks,

Cory,

The RESONANT frequency of a Tesla system is determined by the
the primary capacitance and the primary inductance according to
the formula 1/ 2 x 3.14 x SQRT (LC). This frequency has nothing to
do with the Breaks Per Second (bps) frequency caused by the rotory
spark gap action.  So the ~ 100 kHZ of a Tesla system is NOT set 
by the rotory spark gap action. BTW, there can be up to 3 seperate
frequencies in the output of a Tesla coil: (1) the 50 or 60 Hz utility
power mains frequency (2) the bps caused by the RSG and (3) the 
resonant frequency of the Tesla primary circuit.
