Engineering Possible to simplify or transform source in circuit

AI Thread Summary
Nodal analysis can often be simplified by transforming circuit elements or reorganizing the circuit layout. The discussion highlights the importance of identifying all relevant currents, such as i2, i3, and i4, to ensure accurate matrix input. Participants emphasize the need for clarity in circuit representation to facilitate easier analysis. The original poster expresses uncertainty about their approach, indicating a desire for guidance on proper methodology. Understanding these transformations is crucial for effective circuit analysis.

Homework Statement


I have to do nodal analysis and I was wondering if there is any transformations or simplifications I can do to the circuit. In this class we are supposed to be able to look at the circuit and input what we need into the matrix based on just looking at it. I am not sure that I did it correctly here.

Its been a long time since I've taken these classes but I'll take a look-

I'm looking at your diagram. Where are i2, i3, and i4?
