Homework Statement
Apply the mesh current method to find I0
Homework Equations
Mesh current method
The Attempt at a Solution
On the left bottom square circuit, I set a mesh current, I1, and on the right bottom square circuit, I set a mesh current, I2.
Then, I0=I1-I2.
Since there is a current source on the mesh I1, I1=-5 (negative sign because of the direction.)
and
(1+2+4)I2+22.5=0, so I2=(-22.5)/7.
Therefore, I0=-5-(-22.5)/7=(-12.5)/7.
Am I doing it right?
