Homework Equations
If Capacitors are in series, then (1/C1) + (1/C2) = (1/Cnew)
If Capacitors are in parallel, then you just add them, C1 + C2 = Cnew
The Attempt at a Solution
I'm not sure how to get the equivalent capacitance from here.
Would I just add the 12/7 to the 2uF parallel from it to make one capacitor? What happens then to the 2uF originally in series with the 12/7 uF?
This is what I did: Combine the 3 and 4 uF capacs, then the 12/7 and 2 uF(parallel), then that and 3 uF (series) and then that with the remaining 2 uF and 3 uF, in series.
I ended up with 0.696, which is apparently wrong. Is there a correct way how to resolve all these capacitors? PEMDAS for circuits? Any help will be appreciated
