Engineering Magnetically coupled inductors an AC circuits

AI Thread Summary
When solving problems involving magnetically coupled inductors in AC circuits, the use of dependent sources can help clarify the analysis. The question arises whether these dependent sources require specific polarity, given that AC's nature suggests polarity may not be crucial. It is noted that the angle in AC circuits ultimately influences polarity, allowing for flexibility in assigning values. The discussion emphasizes the importance of ensuring that mesh analysis yields positive results, questioning if this approach is optimal or if alternatives exist. Clarity in the application of dependent sources is key to effectively solving these circuit problems.

Homework Statement



I've actually uploaded the question.

When solving problems with magnetically coupled inductors I like to add dependent sources so that I can keep everything straight. My question is when I add the dependent sources does there need to be a specific polarity to them. With the way that AC works I would think that it doesn't matter what polarity you assign them because in the end the angle is what determines the poliarity. I could make it so that when I do the mesh the sources come out positive. Is this the best way to solve this problem or is there another way.

Thanks
