SUMMARY

The forum discussion revolves around Matt's application of nodal analysis to a circuit problem. He presents his calculations for current flow at node A, specifically i1, i2, and i3, and seeks validation of his approach. The values calculated are i1 = 0.266 A, i2 = -1.67 A, and i3 = -0.598 A. The discussion emphasizes the importance of verifying both current and voltage values to ensure accuracy in nodal analysis.

Let's see

Strategy I checking currents flow at node a make sense:

i1 = 1.33/5 = 0.266
i2 = (1.33-3)/1 = -1.67
i3 = (1.33-4*1.08)/5 = -0.598

Does that make sense?

Note: I plugged your final numbers, I might have misinterpreted what your numbers represent but just wanted to show how you verify your solution.
Strategy II checking if voltages make sense:
If the voltage at node a is vA
and does v0 same as you would get if you apply voltage divider on the most left branch?
