Hello everyone, i'm confused on why i'm missing this problem. Here is my work and problem:
http://suprfile.com/src/1/25o5ux/lastscan.jpg [Broken]

Any ideas?
I know you add up capitors in series like
(c1)(c2)/(c1+c2)

in parellel
c1 + c2 +...+cn

I am presuming the book is using significant digits. Even though it isn't correct most books would interpret "10" as having two digits.

I can't even figure out what "problem" you're trying to solve here. I just see a bunch of different chains of capacitors and a bunch of math scrawled everywhere.

I'm assuming you require the sum capacitance?

I suggest working out the value in full, without rounding at any stage.

Thanks everyone, i was just making sure my technique was right which it was and i did the next problem with inductors and it worked out fine.
