Some time ago I played around with a small (70W) coil. Holding a piece
of copper pipe im my hand I could draw a spark from the TC without
feeling anything. When I aproached my bare hand to the coil, I felt a
tickling sensation, then I got hit by a streamer, and it was quite
painful!
I didn't get burned or something, I was just an "electrical" pain.
An explanation could be that nerves/muscles don't respond to the high
frequency unless the current is very high. If you hold a piece of metal
in your hand, the current is distributed over your skin, but if you get
hit by a spark, the the current enters the skin through a very small
area and it hurts. Any comments?
So long,
Stefan
