My Dad's got 10000uF capacitors for his audio
amps, and they're the
size of a coke can. I reckon 100 such capacitors would fit in my
schoolbag, at worst..."
That's a big schoolbag. I regularly carry five dozen 341-ml aluminum
cans in my backpack (they're iced tea cans, not pop cans, but they're
standard pop-can size), and it's a big backpack and they fill it right
full up. 100 would be five-thirds as much, more like a sports
equipment bag.
And, of course, it depend heavily on the working voltage. a 1Fd 5V cap
is generally smaller than a 1Fd 50V cap. (And, now that supercaps have
shown up, low-voltage caps have gotten even smaller.)
And that's how I learned that school wasn't
going to teach me
anything useful, or basically true.
Well, you'd already learned to sanity-check claims you hear, which is
arguably a more valuable lesson. :-)
