I need to know C1 capacitance, but i cant find a way to solve it without
can you give me a light please?

You have the right idea about computing the frequency.Originally posted by terrakota@Jun 28 2005, 05:51 PM
thanks for reply,
so i must use the :
f = 1/(2)(pi)(Xc3)(c3)
formula? and that frec. applies for the rest of the circuit?
so whats the best formula to solve for c1?
thanks in advance, i'm still a newbie
jaja i dont know why i cant think those solutions by my self, was so simpleOriginally posted by hgmjr@Jun 28 2005, 06:41 PM
You have the right idea about computing the frequency.
The next step is to determine how much current is flowing in the branch containing C2. With the frequency you derived from the information about C3 you should be able to determine Xc2. This will allow you to determine the current flowing through C2.
Once you have the current flowing in the branches containing C2 and C3. You will know the current flowing in C1. You will then have all of the ingredients you need to compute C1.
