1. The problem statement, all variables and given/known data The circuit of the given problem is attached to this post (jpg file). All info is given in the photo. Problem: find VA, VB, IA. 2. Relevant equations Ohms law KCL equations P = VI or V^2/R 3. The attempt at a solution - First, I noted that VB = 9 - VA. - next, i set up a KCL equation at VA: -.004VB + VA/30 + (2VA -18)/30 = 0 - i plugged in VB: -.004(9-VA) + VA/30 + (2VA -18)/30 = 0 - Solved for VA = 6.115 V - Therefore VB must = 2.885 V (given everything so far is correct - by Ohm's law, IA = VB / 15 k ohms - IA = 0.1923 mA - so at this point I have values for all i need to solve the problem, but to check if i was right I wanted to check consv of power. - KCL at VA node = .1923 + 11.54 = IB IB = 11.7323 mA When I checked the power on all 4 items in this circuit, the power did not check out to zero, so somewhere I messed up but I have no idea where.
