moved from general forum so homework template is missing
I was doing the following problem:
And I was asked to find Iy.
I found Iy to be 2.64 using KCL. However, the right answer was negative 2.64.
Is it negative only because there is a dependant voltage source with "+ -" ? And why must it be negative? Does "-" in the final answer play a significant role? If I put positive 2.64 instead of negative, would that be wrong?
Also, here is another question
I found V1 to be 11.9. However, the right answer was - 11.9.
Can someone clarify for me when do you put negative sign ?
