a. Ct = C1*C2?(C1+C2)
Ct = 7*11/(7+11) = 4.28 uF. = Total capacitance.
b. Qt = Ct*V = 4.28 * 9 = 38.5 uC=Q1=Q2
Q1 = C1*V1 = 38.5
7 * V1 = 38.5
V1 = 5.5 Volts.
C2 * V2 = Qt
V2 = 38.5/11 = 3.5 Volts.
c. Q1 = Q2 = Qt = 38.5 uC.
Ct = 7*11/(7+11) = 4.28 uF. = Total capacitance.
b. Qt = Ct*V = 4.28 * 9 = 38.5 uC=Q1=Q2
Q1 = C1*V1 = 38.5

V1 = 5.5 Volts.
C2 * V2 = Qt
V2 = 38.5/11 = 3.5 Volts.
c. Q1 = Q2 = Qt = 38.5 uC.
