    I have been fighting with this problem for hours. If I am thinking right if C3 shorts out it would be like the cap wasn't there and a wire was there instead.
    So I figured C2 and C4 as parellel caps and added them together and which makes 0.02uF. The figured C1 and the 0.02 as a series circuit. I keep getting 0.12 as an answer, which as you can see is not an option. What am I doing wrong??
    If all the caps are good wouldn't the capacitance be 0.15uF? If not I screwed up the other question too.
    I hope someone can explain this to me.
    Thanks in advance

    Does shorting C3 short anything else out?

    Your calculation of a series capacitance is correct, but not applicable here. Think about Steve's question. It should lead you to the correct answer.
