Explanation / Answer

here,

C1 = 3 uF

C2 = 9 uF

V = 90 V

a)

the equivalent capacitance is 3.64 uF

b)

the charge across C1 and 6 uF , Q1 = V * ( C1 * 6 /( C1 + 6))

Q1 = 90 * ( 3 * 6 /( 3 + 6))

Q1 = 180 uC = 1.8 * 10^-4 C

the charge across C2 and 2 uF , Q2 = V * ( C2 * 2 /( C2 + 2))

Q2 = 90 * ( 2 * 9 /( 2 + 9))

Q2 = 147 uC = 1.47 * 10^-4 C

c)

the potential difference across C1 , V1 = Q1/C1 = 60 V

the potential difference across C2 , V2 = Q2/C2 = 16.3 V

the potential difference across 6 uF , V3 = V - V1 = 30 V

the potential difference across 2 uF , V4 = V - V2 = 73.7 V
