Use KCL and KVL to find the power supplied by the two ideal sources

Click For Summary
SUMMARY

This discussion focuses on applying Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL) to determine the voltage across two ideal current sources of 2A and 5A. Participants emphasize the importance of eliminating non-contributing resistors, specifically a 5Ω resistor in parallel with a 4Io source and a 3Ω resistor in parallel with a 5Vy source, to simplify the circuit analysis. The discussion highlights the necessity of labeling mesh currents for clarity in calculations. The use of Ohm's Law is also implied as a fundamental tool in solving the problem.

Hi MHGANAINY, Welcome to Physics Forums!

You'll have to show your work so we can see what's missing or what went wrong.
 
The first thing you should have done is to eliminate the 5Ω resistor in parallel with the 4Io source, and also eliminate the 3Ω resistor in parallel with the 5Vy source. Those two resistors have no effect on the rest of the circuit because they're in parallel with voltage sources.

Did this problem come from a textbook, or a handout given to you by the instructor? :)) It hurts my brain to look at it. Your instructor may be a sadist, in which case we are masochists. :rolleyes:

Show your circuit with the mesh currents labeled, for example as I1, I2, I3, etc. What did you get for the mesh currents?
