  1. i have heard that if there is enough voltage a closed circuit can still give you a shock. even if it doesnt have enough voltage to bridge the gap to the ground or anything like that, i was told you could still get shocked if the voltage was high. any truth to that?

     

    It depends on the power supply and your bodies potential. If your body is charged to +1kV then touching a similarly charged object wont do anything. But if your body does not have a charge or is charged to -1kv then you will get a 1-2kv shock.

     

    The shock wont be as high because the capacitance of your body is relatively low. Current will flow into your body until you reach the same potential as the power supply then current will cease to flow.

  2. to kill requires the P=IV equasion' date=' it`s the Power that kills, not Voltage or Amperage alone.

     

    I`ll gladly spend a day between 2 plates of 1 volt at a million amps potential or several kilovolts arcing at me at virtualy no amps.[/quote']

     

    Thats why I say flowing current rather than just current. Obviously if you stand between 1 two plates charged to 1V almost 0 current will flow.

     

    Electrostatics are not dangerous because the discharge times are so low. a hundred amps may flow but its only lasting for a short amount of time.

  3. OK, I wouldn't really call that high resistance either, but still, it means that if you get a 240V shock it's only like 0.0012A going through you, and you need 0.5A to kill, that'd be more like a 100KV electric shock... that's interesting, then why can 240V kill?

     

    There is no set current to kill. Nobody said that you must have 0.5A to kill, people can and have died from much much lower currents than that. I have heard this number quoted anywhere from 10ma to 9 amps for a woman and 10 amps for a man (no joke).

  4. screw the lungs' date=' why the head ache? or am I the only one that ever gets this from reasonably low concs?

     

    and does it smell vaguely reminiscent of Chlorine gas to anyone?[/quote']

     

    I don't get headaches and I don't think it smells reminiscent of Chlorine gas. :P

     

    I think it smells nice and clean and slightly sweet.

  5. Wow' date=' I guess my liking the smell of ozone is odd. Too bad it destroys the lungs.

     

    I forgot some. I also hate sulfur dioxide, nitrogen dioxide, and acetone. I like menthol.[/quote']

     

    Ozone only destroys the lungs in high concentrations but is detectable in very low concentrations. The same is true for many of the other chemicals on this list

  6. If you use web hosting I would go with DSL because the upload speed is equal to your download speed. With cable up speed is half as much.

     

    It seems that the provider choice is more important than the DSL/cable choice though.

  7. I also have (somewhat) severe OCD, but I find the idea of becoming like Howard Hughes more appealing than scary. Howard Hughes was more than just a basket case, and I consider him to be a great man.

     

    What I'm trying to get at here is that most disorders come with more than just negative side affects, and its hard to say but do you think Howard would have accomplished all he did without OCD?

  8. When I was mowing the lawn a few years ago I was turning around at the fence and pushed against it with my arm to gain a bit of momentum. I few minutes later I felt a burning sensation in my arm and I looked down and saw around 500 splinters in my arm.

     

    Almost as stupid is when I used a needle to dig most of them out.
