Default can someone explain the physics behind this?

Yesterday it was 34 VAC.

Take one standard grounded computer cable.
roll over it a couple of hundred times a day with a chair. (Note the bottom loop from the tie wrap.)

Voila!

It looks like you ran over the Fluke 23, too.

Double check your leads.

The more it gets run over, the more volts fall out of it?

An autopsy proved the hot was cut in two and the neutral was shorting to ground.

The voltage was due to the capacitance of the air gap between the ends of the broken conductor.
