[sdiy] Grounding & computers

[Sowa Roman]

There are two capacitors in range of few nF from both wires (hot and
neutral)
going to ground wire. If there's no ground pin in your socket, everything
which
is connected to 'ground' in your computer is connected to this capacitive
voltage
divider, hence 110V. They are small capacitors, that's why you're still
alive
after your experiment with touching PC and TV at once.

""Hi list,
""
""Talking about all this grounding stuff, I wondered if you 
""could answer this
""grounding question I've been wondering about for a long time.
""
""My computer isn't grounded. I don't even have a ground socket 
""here in the
""room. The mains voltage here in Europe is about 220 V. Now 
""why is it that
""the voltage level of my computer casing has to be at 110V 
""from earth level?
""If I touch the computer casing with one hand and the grounded 
""cable tv plug
""with my other, I can do some nice instant Michael Jackson 
""dancing stuff
""without any practicing... Now why did they do this?
""
""Cheers,
""Martijn
