Re: [World] The truth about electricity
The higher voltages are the basis for the arc lighting that is used on
buildings and poles. It requires a high voltage to get it to work. The
same is true for the neon and argon signs. The "jacob's ladder" seen in old
horror movies and science fiction movies used two separated wires (contacts)
that arced and the sparks would ride up the two wires being closer together
at the bottom and farther apart at the top which would cause the arc to
stop. The unit uses a 20,000 volt neon transformer to accomplish the feat.
When I was in high school, a kid built one as a science project. It
requires very high voltages, not amps to get the electricity to arc between
the contacts. I remember it was a pretty cool demonstration.
At low voltages, normally, contact is needed to start an arc. This is the
whole idea in doing arc welding. You have to scratch (make contact) with
the metal surface with the welding rod and then make an arc. If you lift
the rod too high from the metal surface, the arc ends and you have to start
over again. This is done at voltages of 220 and under, ac and dc.
