I'm going to turn to another subject but almost in the same line of discussion.
I have a line tester consisting of a screwdriver (the probe) connected to a
neon bulb connected to a metal cap on the end which I'm suppose to touch.
If the screwdriver comes
in contact with a hot wire the neon will glow. How does this work? I must be
"ground". I obviously have a different potential than the hot wire but how?
I don't understand this. Can someone define "ground"? Will the difference in
potential eventually equal and the neon stop glowing? Do I recharge myself by
making static? Since I am insulated (shoes, rug, etc) from earth ground am I
a floating ground? What does this all mean?
