Explanation / Answer

C1 = 0.5 uF

C2 = 1.4 uF

V = 20 volts

C1 and C2 is series

1 / C = 1 / C1 + 1 / C2

1 / C = 1 / 0.5 + 1 / 1.4

1 / C = 2 + 0.714 = 2.714

C = 1 / 2.714

C = 0.368 uF

Part B :

the charge on each capacitor is Q = C X V

Q = 0.368 X 10-6 X 20

Q = 7.36 X 10-6 C

Part A :

V1 = Q / C1

V1 = 7.36 X 10-6 / 0.5 X 10-6

V1 = 14.72 volts

V2 = Q / C2

V2 = 7.36 X 10-6 / 1.4 X10-6

V2 = 5.25 volts

Part D :

C = C1 + C2

C = 0.5 + 1.4

C = 1.9 X 10-6 F

Q = C X V

Q = 1.9 X 10-6 X 20

Q = 38 X 10-6 C

Q = 38 uC

PArt C :

V1 = Q/C1

V1 = 38 X 10-6 / 0.5 X 10-6

V1 = 76 volts

V2 = Q/C2

V2 = 38 X 10-6 / 1.4 X 10-6

V2 = 27.14 volts
