Answer: 6

  1. The wires make the first three 8 μF8\ \mu\text{F} all lie between A and one node N: parallel, 24 μF24\ \mu\text{F}.
  2. The 4th and 5th capacitors form a closed loop hanging from N with no other connection, so they carry no charge.
  3. The last 8 μF8\ \mu\text{F} is between N and B.
  4. CAB=24×832=6 μFC_{AB} = \frac{24\times 8}{32} = 6\ \mu\text{F}
  5. Answer: 6 μ\muF
