"Fundamentals of Electrical Engineering" Circuit Basics Question
I am asked to find p1, p2, p3, p4.
p=vi
ƩP=0
p1=(5)(-9)
=-45
p2=(2)(9)
=18
p4=(3)(5)
=15
p3=v(.6i)
=v(.6(4))
=v(2.4)
I know that v=5 and p3=12, but I don't know why v=5.
I do perfectly fine finding p1, p2, and p4, but I am having difficulty figuring out how to find the voltage on p3 to get the power. I am trying to refrain from using the law of the conservation of energy (ƩP=0), since a previous example I tried to figure out before gave me the same problem.
