Explanation / Answer

Remember:

For parallel combination

Ceq = C1 + C2 + C3 +...............

for series combination

1/Ceq = 1/C1 + 1/C2 + 1/C3 + ............

for 2 capacitors in series it will be

Ceq = C1*C2/(C1+C2)

Using this Information:

Part A:

C = C1*C2/(C1 + C2)

Part B

Using given values:

C = 34*9.5/(34 + 9.5)

C = 7.4 uF

Part C

Relation between charge and capacitance is given by:

Q = C*dV

Part D

Using given values:

Q = 7.4*10^-6*14

Q = 1.04*10^-4 C
