Homework Statement
Use the node-voltage method to calculate the power delivered by the dependent voltage source.
Homework Equations
i1+i2+..in=0(KCL)
i=v/R
p=i*v
The Attempt at a Solution
I posted the solution below, but I'm going to post my own workings, based on just the circuit. I'm confused how they got their answer in the solution.
My workings:
v0-160/10Ω+i0/100Ω+150i0/50=0
I can reduce it to say i0*x=v0*x but I don't see how I could solve for either.
In their solution,they have (v0-150i0)/50 for the last part. Wouldn't it not be v0, since it's a different source?
Also, I have two unknowns, why did they only use one equation? I'm unsure of when I have to use one or two or more equations for node voltage questions. In this question, I felt like I would need two equations to solve it, but their solution only has one.
