My knowledge of AC voltage is very basic but I have a question.
I stumbled upon this by accident.
If you take a piece of aluminum, stick one one end into the ground just a little, say 1".
Then take a volt meter, stick one lead into the ground, the other lead anywhere on the aluminum above the ground, you get a small AC voltage reading.
It seems to have a higher reading with thicker aluminum than thin but it is a consistent reading with anywhere from .8 - 1.50 Volts AC.
Aybody know of this and what the source could be?
