BEFORE YOU READ THE REST: Problem (f) is the only one I need help with. Thank you! I have already confirmed all my other values as correct in my online program! 1. The problem statement, all variables and given/known data In the figure a potential difference V = 150 V is applied across a capacitor arrangement with capacitances C1 = 14.8 µF, C2 = 4.27 µF, and C3 = 4.22 µF. What are (a) charge q3, (b) potential difference V3, and (c) stored energy U3 for capacitor 3, (d) q1, (e) V1, and (f) U1 for capacitor 1, and (g) q2, (h) V2, and (i) U2 for capacitor 2? http://edugen.wileyplus.com/edugen/courses/crs7165/art/qb/qu/ch0/EAT_13632548498390_6123878003864797.gif C1 = 14.8 µF C2 = 4.27 µF C3 = 4.22 µF V1 = 33.5 V V2 = 116.4 V V3 = 150 V q1 = 496.5 µC q2 = 496.5 µC q3 = 633 µC U1 = (NO IDEA) I keep getting anywhere from .00830 to .00831 and .00832 U2 = .0289 J U3 = .0475 J 2. Relevant equations q = V*C 1/CT = 1/C1 + 1/C2 + ... + 1/Cn (for a series) CT = C1 + C2 + ... + Cn (for parallel) U = (1/2) q^2/C = (1/2)QV = (1/2)CV^2 3. The attempt at a solution So basically, I have solved for everything except problem (f), which I don't understand because my values for U2 and U3 were correct. I have tried every variation of the stored energy equation, and have tried all forms of significant figures (my program does uncertainty +/- 1 from the 3rd significant figure). I have also wondered if maybe the fact that the electrons travel through C2 first, before reaching C1, that it may have some effect upon the stored energy of C1, and I have tried adding, subtracting, you name it, the two values. I'm kind of stuck at this point.
