Homework Help: Adding up capacitors in series/parelle, the book got a slighty diff answer?

  1. Feb 26, 2006 #1
    Hello everyone, i'm confused on why i'm missing this problem. Here is my work and problem:

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

    in parellel
    c1 + c2 +...+cn

    it seems to book has rounded down the result!

    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.
