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 = 010V - i''*20Ω - 2V = 5Ωi2 - 10V
10V - i''*20Ω - 2V - 5Ω*i'' + 10V = 0
18V - 25Ω*i'' = 0
18V = 25Ω*I''
I'' = 0.72 AAny 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?
