Theres two current sources and three voltages sources the problem wants to know the power supplied by each current source
according to the book the problem can be solved using Kirchoffs current law and kirchoffs voltage law
The answers according to the textbook the 2mA current source supplies 6mW and the 1 mA current source supplies -7mW
The Attempt at a Solution
I can only guess that they subtract the 5v by the 8v then multiply the result by the 2mA.
Also subtract the 15v by the 8v and multiply the result by the 1mA source to get the -7mW answer.
