1. The problem statement, all variables and given/known data Find the power supplied by the 3-A current source in the network in the Figure using loop analysis: Figure: http://i.imgur.com/OcDUuhX.jpg 2. Relevant equations KVL applied to 1 mesh and 1 super mesh, 1 source equation 3. 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.
