Electric Circuits - Superposition and Mesh Analysis

Click For Summary
SUMMARY

The discussion focuses on solving Exercise 4.15, which involves calculating the current I using the superposition theorem and mesh analysis. Participants highlight the importance of correctly applying mesh analysis, particularly in circuits where current divides, such as at the junction of a 2Ω and a 3Ω resistor. The feedback emphasizes the need for careful examination of current distribution to identify errors in calculations.

I think i am doing the mesh analysis wrong, but can't see where. Can someone give me feedback?

Thank you, ppl!

Where the 2A current divides---some goes through the 2Ω and some goes through the 3Ω---these will not be equal currents.

I anticipate that when you take a closer look at this part of your working you will spot your mistake.
