i keep getting stuck in this problem, i dont see what im doing wrong.(adsbygoogle = window.adsbygoogle || []).push({});

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

Im 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. Im just not sure if im 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.
