Some people do, some people don't feel slight shocks. I can feel 18 V
But really feel the 60 Vac centertap of an ungrounded computer. Assume the other path is capacitance since I was insulated elsewhere from ground. Just drag your knuckles along the metal and you'll feel it. - Robert - On Mon, 29 Nov 2004 09:47:00 -0700 drcuthb...@micron.com wrote: > There is the body capacitance of about 100 pF having a > reactance of 27 M > at 60 Hz.
