i keep getting stuck in this problem, i don't see what I am doing wrong.
the problem says to determine which sources absorb positive power, then show that algebraic sum of the five absorbed power values is zero.
i have attached a picture of the circuit, and here is what i have done:
Starting from left to right,
p=-4W
p=-16W
p=40W
p=-50W
p=-30W
I am not getting the sum to equal 0.
From what i understand, when current is going from + to - in a independent voltage source it is charging and when it is going from - to + it is releasing power, and that is the guidelines i have used to get the bove answers. I am just not sure if I am supposed to follow the same guidelines for independent current sources. Is there a website that discusses these topics, kuz my book has not done a good job to demonstrate these ideas very clearly.
