I am too lazy to log into yahoo and view the photo, but I suppose you
are talking about the single loop of wire that is wound around both
outside legs in a figure of eight pattern?

Re: Deane Kidd and the Metric System
Hello Albert,
Don't know if I understand the joke, but it stroke me to ask...
What are those "equalizing loops" for? I always wanted to know.
Likewise, in some AC motors (Squirrel Cage type), there

Re: Tektronix Type 575 Transistor Curve Tracer  $75 (Syracuse)
IMPORTANT: This is a MOD C122 575. That is special. It goes to 400V instead
of the more common (nonmod) version. That is definitely worth $75.

Re: Tek CRTs may not be metric after all
Hi David,
I'm sure you're right about the physics Tek used being metric. I didn't
think about that until you mentioned it.
Also, its logical to use cm for another reason: All the electrical units

Re: Deane Kidd and the Metric System
The rules are complex. If the denominator is of the form 2^n x 5^p it is a simple nonrepeating
fraction ending in an infinite number of zeroes.

Re: 7904A readout bounce
David,
I haven't tried to look at this effect (moving the beam position) and
its relation to the readouts.� Does it depend on which scope you are
using and the range selected.� Seems like higher

each other that are not repeating.

Guys,
I think what Ian Newman meant is that you can easily do that conversion by
heart, without resorting to a calculator or a piece of paper to make the
full division or multiplication

just ask the Google Home I keep in the shop: Hey Google, what's 283.4mm
in inches? And she tells me.

It makes pi*pi == g == 10 look boring.
