What is it? Set 535

Sounds like a good answer to me but I'm still looking for a reference.

The rest of this week's set have been properly identified:

If the resistor looks familiar it's because I posted it once before around seven years ago.

I'm glad at least a couple of them can be identified. Such a loss when people have no idea what it is.

What loss? We just need to think harder! ; )

It's called a "Kelvin connection", though the only thing the extra terminals do is nullify any error caused by the leads on the resistor itself. You don't need a four-terminal resistor to use a Kelvin connection.

Or maybe it's an item we no longer need, like buggy whip straightener.

Whether we "need" it or not has nothing to do with the challenge. Obviously, most of these items are obsolete as of the current date.

But some of them are Not obsolete as examples of man's creativity and ingenuity! That's part of the beauty of it.

Talking to yourself again Bill?? :-)

I won't go into details, but I've made a career out of being able to talk with myself! Sometime the arguments get really heated! ; )

Yeah, and he's stubborn too!

But have they ever come to blows?

I'll bet that you could get the information from GE, since it has the part numbers on it.

Oh -- before I started posting in this thread, I think. Anyway, the resistance and current on that support my interpretation there -- the full-scale voltage is significantly higher than most modern shunts (which aim for 50 mV full scale. This one is 1.5 V full scale, (or 1500 mV if you prefer).

Enjoy, DoN.
