RE: Output





Would it be possible to measure voltage output of a Tesla Coil with a flux
density meter? Or would you not be able to get close enough to do any good?
Just a thought.

Hi all,

I do recall a Dicovery Channel special on lightning that had a clip 
showing Richard Hull's 11-D magnifier in operation for the man-
made lightning segment and the narrator stated, "these 2 million
volt sparks leap 10 ft. thru the air and are an awsome reminder of
the raw power of electricity". I know because I have it on tape. Al-
so, John Couture's "Tesla Coil Construction Guide" on pg. 14-9
has a "Sphere Spark vs Kilovolts" log graph which seems to show
that ~50" represents 1 million volts. I believe this is referring to 
electrostatic DC charges built up on very large radius spheres, 
though and was the only comparison data available to John C. -at-
the time of printing (1994). If I'm not mistaken, John stated this
himself? Also, this same graph shows that 100" sphere sparks 
are considerably less than 2 million volts ( KVs vs spark length
is NOT a linear progression).


My $.02 worth,
