In Fig. 25-22, each capacitance C1 is 7.2 µF, and each capacitance C2 is 4.8 µF
(a) Compute the equivalent capacitance of the network between points a and b.
(b) Compute the charge on each of the three capacitors nearest a and b when Vab = 450 V.
(c) With 450 V across a and b, compute Vcd.
The Attempt at a Solution
I tried figuring the total capacitance, but I can't tell what is series and what is parallel! In series I know that the potential differences add up in series and they are the same in parallel, and the opposite is true for charge. Please help!
