A couple of neighbors were bickering about this.
Lets say there is a 100' extension cord (with metal copper conductors)
energized by a live household 120V 60Hz outlet. Nothing is plugged into
the cord, and it's one without any indicator lights or ground fault
gimmicks. Said cord is dry, other than the typical indoor humidity of a
normal household garage.
How would one calculate the minuscule energy loss from such a static
conductor just sitting and radiating (and/or whatever).
I tend to agree with the one neighbor that there's bound 'some' loss...
but probably on the order of, oh maybe a penny's worth every few
centuries; but haven't a clue as how one would calculate something like
this, or even what loses would be involved.
Inquiring minds and all that... Thanks in advance!
