For grins, I just tried the experiment with a couple of 220uf caps that measured close to the same value. I got about 110uf with them connected in series either way. I used a Tektronix DMM850 and an old Heathkit C-3 to make the measurements. The C-3 read a little low (about 100uf). |
Ditto herre. Two 10uf electros connected in series back-to-back (-++- or +--+) yield the proper division by two, albeit about 10% high at 5.6uf. New and used single unit Non-polarized caps reading 2x the value is odd.
We've got an LC53 at work - guess what's going with me tomorrow?? There's also a college professor friend of mine I'll contact - his doctoral thesis was on dielectrics and electrostatics, a good read if you can stomach the math and physics. He worked with NASA while a graduate student - awesome labs!
Cheers,
