Homework Statement
A 9.0 uF and 4.0 uF capacitors are connected in parallel, and this combination is connected in series with a 12.0 uF capacitor.
a) what is the net capacitance?
b) if 32 V is applied across the whole network, calculate the voltage across each capacitor.
Homework Equations
In parallel, capacitance add together C = C1 + C2
In series, 1/C = (1/C1) + (1/C2)
Q = CV
The Attempt at a Solution
I was able to find part a) to be 6.24 uF.
For part b), this is what I have:
Q = CV = 6.24 * 10^-6 F * 32 V = 2.0 * 10^-4 C
For the 12 uF:
V = (2.0 * 10^-4 C) / (12 * 10^-6 F) = 16.64 V
For the 13 uF (9.0 and 4.0 in parallel):
V = (2.0 * 10^-4 C) / (13 * 10^-6 F) = 15.36 V
My question is will the 9.0 and 4.0 uF have the same voltage as the 13 uF or will I have to do the same for each 9.0 and 4.0 uF capacitor?
Thanks
