What does the 4p indicate? Dont know about the
complications involved with an arc gap as you are
asking, but I am confused here on your initial
assessment. The cap energy storage is noted as .5CV^2,
which tranfers twice per cycle, meaning that for 60
hz, a 120 fold multiplication should give the energy
transfer. Is your 4pF= 120? (for 60 hz)
