1. The problem statement, all variables and given/known data For the cicuit shown, the voltage is 200V, C1= 4microF, C2= 15microF and C3= 12microF (i drew it on paint) Find a) the equivalent capacitance between the terminals b) the charge stored on each capacitor c) the total stored energy 2. Relevant equations Ceq= 1/c1 + 1/c2 +1/c3 or Ceq = C1+C2+C3 C=Q/V I think this is the right equation for the energy stored in a capacitor: U= QV/2=CV^2/2 3. The attempt at a solution Ok i'm really not sure because i'm having a lot of trouble with figuring circuits out. I think C1 and C2 are in series but in parallel with C3. For a) what i did is : Ctot = 1/Ceq + C3 and 1/Ceq = 1/C1 + 1/C2 Therefore Ct = 3.15microF + 12microF Ct= 15.15microF b) I would use C= Q/V so Q1 = 8*10^-4 C Q2= 3*10^-3 C Q3= 2.4*10^-3 C c) U=CV^2/2 my equivalent capacitance was 15.15microF and my voltage was 200v, therefore my U should be 0.303J It seems to me that b and c were too easy to get. Besides, i'm not even sure my a) part is right. I'm so confused.... the picture i drew is at the bottom, it's just pending approval.
