1. The problem statement, all variables and given/known data Given, What is the charge on C2 (the highlighted capacitor). The answer is supposed to be Q2 = 5 uC 2. Relevant equations C=Q/V Loop Rule? 3. The attempt at a solution What I did, is using the loop rule on the smaller loop, I set up V2 - V3 - Vof C2 = 0 6 V - 4 V = Vof C2 2 V = Vof C2 So since, Vof C2 = Q2/C2 Then, Q2 = (2 V)(5.0 uF) And Q = 1.0x10-5 C, however that isn't the answer... It's supposed to be 5 uC. Solution Wow, I just figured it out, stupid mistake. It should be V2 + V3 - Vof C2 = 0. That fixes it.
