For the capacitor network shown in the figure, the potential difference across ab is 12V. Find (a) the total energy stored in this network and (b) the energy stored in the 4.8 uF capacitor. figure: http://i.imgur.com/Wxbuu.png ATTEMPT: PART A: i first did the leftmost 2 capacitors and got C=3.1E-6. then i did the top 2 capacitors and got C=1.4E-6. then i used those top 2 as a parallel capacitor with the bottom one getting: 4.9E-6. i added them all together to get C=9.39E-6. using the forumla u=.5CV^2 i got U = 6.76E-4 J. did i do this right?
