Homework Statement
We have the circuit in the figure.I have to find the average power consumed by all the elements and the source.
Homework Equations
P=0.5*(I^2)*R
P=-VmImcosθ/2
The Attempt at a Solution
The inductor consumes zero inductive power.
I apply nodal analysis at node Vo
We have (6-Vo)/3=Vo/6
Vo=4
Here I find that I1=(6-4)/3=2/3
So the average power dissipated by 3 ohm
P=0.5*(4/9)*3=2/3 W
Current through 6 ohm is Vo/6=4/6
P=0.5*(16/36)*6=4/3..problem is ,in my book power dissipated by 6 ohm is 10/3...
Now,the power consumed by the source is
P=P=-(2/3)(6)cos0/2=-2 W...but the result in my book is -4W
Where is my mistake?
