Re: [TCML] Terry Filter Resistors
Hi Phil,
Don't be amazed. It's far more fun to reinvent the wheel. Happens to
smartest of people. Funny, the senior 20 year top CE at work did
something similar in a mechanical design. Imagine a set screw (1/2"D x
1.5"L) with a jam nut on the end. To keep a long story short, he pretty
much reinvented the "bolt" since the set screw always ended up flush to
the nut (no need for distance variation as one would assume in such a
design). I still get a chuckle every time I think of it (and yes,
engineering replaced the set screw and nut with a "bolt"). This sort of
thing happens all the time in every aspect of engineering. Why should we
be any different?
Actually, the measurement was odd. I might expect a 1/2W carbon resistor
to freak out the LCR, but a dimension like 0.75" x 6", I would have
expected a decent reading. Gary was wise enough to see the forest for
the trees. Someone like me looking at a wire wound resistor inductance
for the first time needs someone like Gary to point out the oddity. Matt
helped with separating the R from the L. Then Terry listed Nichrome as
material used. Those bits of data all put the pieces of the puzzle
together. And finally, Shaun called Ohmite and retrieved the
inductances. All makes sense now.
Peering at the archives would have shown a low L statement. But the
question to why would still have lingered and maybe without an answer.
So, although the archives are great, there's nothing as good as a fresh
discussion. That's sort of been my take on the archives. I like them as
their good for data, but not everything to be discovered is there, and
sometimes, hands-on discussions, even if old, are far more helpful.
Take care,
Bart
