Explanation / Answer

We fave c1 and c2 in series combination, so

1/Ceq=1/c1 +1/c2

1/Ceq=1/5.2 + 1/3.9

Ceq=5.2*3.9/(5.2+3.9)

Ceq=20.28/9.1=2.2

It is now in parallel combination with C3

So Ceq of c1, c2 and c3 is

Ceq=2.2 +c3=2.2 +9.1=11.3

Now all the capacitors (ceq and c4, c5 and c6) are in parallel combination so

We have

Cnet=11.3 +2.9 +0.95+15=30.17 micro farad.
