Equivalent Capacitance with Kirchhoff's Laws

[kassu]

Homework Statement

So that is my problem

I know that I have to use Kirchhoff's Laws to find the equivalent capacitance. I am just suck on how to set up those equations. I know how to do it with resistors, using V= IR. But I don't know where to use the current here, since capacitors are C = Q/V.

Any help?

There might be more than one way to go about this problem. But I think one way that might work out nicely is to convert each capacitor to its impedance, Z. In other words, analyze the circuit in the s-domain or phasor domain (a.k.a. Fourier domain, a.k.a. jω domain). (The s-domain might be the simplest.)

That way you can use Kirchhoff's Laws noting that V = IZ.

You can use the approach I laid out for resistors in this thread
