    Whats the most that static electric shock can put out. At work earlier, I got a big charge of it and when my finger got near a piece of metal, I saw and heard the spark... a bright flash, and I felt it in my finger for a few minutes after.

    it takes roughly 30,000 volts to bridge a gap, a little less if there is more current(amps) but a static spark is anywhere from 15,000 to 30,000 volts, and very little amprage,

    id have to look it up to get you the exact voltage and amp ratings

    That sounds about right to me. You need ~3000000 volts/meter to ionize air.

    Guess what lightning is! Static on a massive scale.

    I can tell you that a CH-53E helicopter can produce over 65,000V of static electricity while hovering. When lifting external loads, the ground crew has to keep a grounding wand in contact with the cargo hooks at all times when connecting the load slings, otherwise the hook-up guy will get zapped HARD (I once watched a Marine get knocked off a 5-ton truck because the grounding wand came off the hook just before he touched it. Our external-lift training mission turned into a no-sh*t medevac...). At night, the spark between the grounding rod and the hook is plainly visible to the naked eye, and is about 6" long... Pretty cool.
