We had the Fluke version of the differential voltmeter in my lab at TI in the 60s. I don't think they have changed much in theory since then.

No, most theories change very slowly and rarely if at all over time. Ohm's law is still hanging in there.  smiley-wink

Yep, Ohm's law is not gong to change because it is a definition and by definition, true.  smiley

Except near the speed of light, eh?

I'm waiting for "Ohm's Law of Relativity".

Don't bother waiting. I saw the movie, the cat dies.
