That would constitute a measurement. The act of doing this would make
the cable live, or dead.

No it would not.




Unless you can prove otherwise :-)


Try it and let us know.

That's not proving otherwise. Connecting any load is in fact making an
observation, whether the load be a DMM or an organic breathing entity.

then define load?, is the insulation around the conductor a load ?
IS the air a load, the only thing that can't be considered a load is a vacuum.

I know of a Mr Maxwell who might have disagreed with you over the
vacuum, depending how long the wire is and how fast the voltage is
changing.

A true genius! I find it amazing how someone could predict wireless,
Terry Wogan and Monty Python even before Marconi was born.

The only load in a vaccum would be the insulation. A conductor on its
own would remain unobserved and thus neither dead nor alive.

Such a postulation would be very silly though, because you could not
have a vacuum. Assuming it occupies the same universe there will be no
vacuum as only a few million light years from the subject there will
no doubt be metals or charged gasses for it to affect.
