1. Select loop currents.
In this case we use meshes.
We note that the current source
could define one mesh.
2. Write loop equations.
Loop 1
Loop 2
Loop 3
Since we need to compute Vo it is
efficient to solve for I3 only.
HINT: Divide the loop equations by 1k. Coefficients
become numbers and voltage source becomes mA.
3 non-reference nodes. 3 meshes
One current source, one super node
SELECTING THE SOLUTION METHOD
BOTH APPROACHES SEEM COMPARABLE. CHOOSE
LOOP ANALYSIS
We use the fact that
I1 = Is
Loop 2
Loop 3
