(a) Cc and Cd are in series, so their equivalent capacitance= C1= (1/8+1/7)^-1 =3.73uF
c1 and Cb are in parallel, their equivalent capacitance= C1b= 3.73+5= 8.73 uF
C1b and Ca are in series, so the total equivalent capacitance= C= (1/8.73 +1/3)^-1
C=2.23 uF = 2.23x10^-6 F
(b) C= 2.23uF and Vab=12 v
so total charge= Q= C Vab
Q=2.23(12)=26.8 uC
Ca=26.8 uC=2.68x10^-5 C.
Va= Qa /Ca= 26.8/3=8.93 V
so the volatge across the parallel part of circuit=12-8.93=3.07 V
so Qb= Cb Vb=5(3.07)=15.34 uF= 1.534x10^-5 C.
Qc=Qd= Vcd (Ccd)=3.07(3.73)=11.46uC= 1.146x10^-5C
