Homework Equations
[tex]P=VI[/tex]
[tex]P=I^2 R[/tex]
[tex]V=IR[/tex]
The Attempt at a Solution
The part a is all correct.
[tex]i_\wedge = 5A[/tex]
[tex]i_o = 2A[/tex]
[tex]v_o = 80V[/tex]
This is what i have done in part b but it is not correct because P_delivered not equal to P_absorbed.
[tex]P_d = (50*7)+(20*40)[/tex]
[tex]P_d = 1150W[/tex]
[tex]P_a = (5^2*18)+(2^2*40)+(8*5)(20)[/tex]
[tex]P_a = 1410W[/tex]
I am not sure if the dependent voltage source is power absorbed or delivered.
Can somebody explain to me what have they done in the part b answers. For instance how did they get the values for [tex]i_g[/tex]?
