Homework Statement



Hand-drawn circuit schematic between terminals a and b, with capacitor symbols on the wires forming a network of nested rectangles.

Homework Equations

The Attempt at a Solution



I really have no idea how to proceed. Applying Kirchoff's laws to this would be quite lengthy. This circuit is supposed to be a wheatstone bridge but I can't see it.
 
See on internet some stuff about the star-delta transformations.
I don't want to say useless things, but I would apply this method here.

Actually, there is a Wheatstone Bridge (5 caps), but the Bridge is in parallel with 1 cap.

Oh I see it now. Thanks!
