VA and stored energy in capacitors



Original poster: "Jolyon Vater Cox by way of Terry Fritz <twftesla-at-qwest-dot-net>" <jolyon-at-vatercox.freeserve.co.uk>


Since relationship between apparent power (VA), frequency (F) and stored energy
(E) in a capacitor in an AC circuit is VA=4pFE, where it is assumed that F is
the line frequency (50 to 60 Hz) during the period when the capacitor is being
charged by the transformer prior to the firing of the spark-gap, doesn't the
same equation apply when the gap fires when F becomes the resonant frequency of
the Tesla coil primary? 

Does this not go some way into accounting for high peak powers observed in TC
discharges?
