## Homework Statement

Find the power supplied by the 3-A current source in the network in the Figure using loop analysis:

## Homework Equations

KVL applied to 1 mesh and 1 super mesh, 1 source equation

## The Attempt at a Solution

-To start off, I defined all my currents to go in the counter-clockwise direction.

-From left to right, I labeled the loop currents as IX, I2, I3, & I4 (I4=3A)

-Next, I constructed my source equation:

2IX=I2-I3

-For my IX loop, I wrote down the following:

IX*4 + 50 + (IX-I2)*4 = 0

-Considering there is a current source between I2 and I3, I wrote down a super mesh equation:

(I2-IX)*4 + (I3-3)*5 = 0

So, that's 3 equations and 3 unknowns, but I know one of my equations is incorrect because solving that system results in ridiculous currents, on the scale of ~20A.

Where did I go wrong? Thank you.
