Homework Statement
The question asks for current I1 and I2.
Homework Equations
The Attempt at a Solution
I managed to get the answer using KCL at a few different nodes, but I am unsure why my first attempt was wrong.
For question 3a, I tried using KVL at the left most mesh.
My equation was: 3 * R1 + (-I1)* R2 = 0
and my answer for I1 using this method was 7.5A.
And why can't I use the following KCL equation to find I2:
KCL at node V1: I2 = 12/R4
which will give me I2 = 1.71A
And why do we only consider the small loop when calculating the power delivered by the 3A current source?
I'm quite weak in this subject, and my quiz is next tuesday so I would you all can help me out. Thanks
