It's me again, still reading AoE 3rd. On page 40, footnote 35, the author writes:
Resonant charging is used for the high-voltage supply in flashlamps and stroboscopes, with the advantages of (a) ......, and (b) no current immediately after discharge (see waveforms), thus permitting the flashlamp to “quench” after each flash.
The waveform looks like this:
So why can resonant charging produce "no current immediately after discharge" but resistive charging doesn't? And I didn't see a current waveform.
