Explanation / Answer

a)

C3 and C5 are in series and their combination is given as

C35 = C3 C5/(C3 + C5) = 4.5 x 4.5 /(4.5 + 4.5) = 2.25 uF

C4 , C35 and C2 are in parallel and their combination is given as

C2345 = C4 + C35 + C2 = (4.5/2) + 2.25 + (4.5/2) = 6.75 uF

C1 and C6 are in parallel and their combination is given as

C16 = C1 + C6 = 3 + 3 = 6 uF

C16 and C2345 are in series and their combination is given as

Ceq = C16 C2345 /(C16 + C2345 ) = 6.75 x 6 /(6.75 + 6)

Ceq = 3.2 uF

b)

V = 17

charge stored is given as

Qeq= Ceq V = (3.2) (17) = 54.4 uC

c)

V1 = Voltage across C16 = Qeq/C16 = 54.4/6 = 9.1 volts

d)

q1 = C1 V1 = (3) (9.1) = 27.3 uC

e)

V2 = Voltage across C2345 = Qeq/C2345 = 54.4/6.75 = 8.1 Volts
