Why Is 47 So Popular In Electronics?

Some people, especially the folks who make power resistors, tend to ignore the "E" series, and make things like 50 ohm 10% resistors.

We, like a lot of people lately, prefer to use only 1% resistors, the E96 series.

We avoid leading zeroes and small integer values, too. Like your

0.00047. 0.33 uF is 330 nF to us.

You're not really serious are you Brett?

Oh, he is.

I know Bret from other groups. You are probably correct.

OK, here's a more difficult question:

Why do 16" diameter flour tortillas come in packages of 10 that weigh

3.20 lbs?

Why is it so important for a flour tortilla to weigh 0.32 lbs +/- 0.05 lbs?

That comes out to be 5.12 oz or 145.3 gms.

The weight is not important, the ability to see the loss in weight is. Less weight = more dry.

A much more serious question is why hand tools come in packaging that requires a cutting torch to open, while light bulbs are sold in the flimsiest cardboard known to man.

Except for CFLs. A while back (when they were still $10 each) I had one whose plastic packaging seemed to be bomb-proof. I slit along one edge, and as I struggled to free the little beastie, it launched itself skyward and self-destructed when it hit the dining room table. This was definitely a case of "ten dollars a pop"... with a real "pop" !

I use my *band saw* to get into modern blister packs. I slice open three sides. It's fast, easy and noisy. What's not to like?
