1. The problem statement, all variables and given/known data http://imageshack.us/a/img834/5512/homeworkprobsg216.jpg [Broken] Using superposition, find i. 2. Relevant equations V = IR, KVL, KCL, Nodal / Mesh analysis, voltage division, current division Superposition procedure 3. The attempt at a solution So this time the dependent source is a voltage source but there's a current relation, and all 3 are voltage sources. I know for superposition you're supposed to silence voltage sources 1 at a time and then find the current through each of those times and then add. But not sure what to do if there's a dependent source / 3 sources in a circuit. I think you silence the 2i since it's a voltage source so it's shorted so: I' + i'' + I''' = 0 I think it goes: I': 2v silenced I'': 2i silenced I''': 10V silenced for i'' (2v silenced) and trying mesh: i'' - i2 = 0 i think would be the mesh current down the 10V 10V - i''*20Ω - 2V = 0 and then 5Ω*i2 - 10V = 0 10V - i''*20Ω - 2V = 5Ωi2 - 10V 10V - i''*20Ω - 2V - 5Ω*i'' + 10V = 0 18V - 25Ω*i'' = 0 18V = 25Ω*I'' I'' = 0.72 A Any tips as to how I what I can do about that dependent source now? Is it possible to use mesh analysis with it? How? Or can I also use nodal?
