Hello,

The assignment says find the magnitude and phase of V0 using mesh current analysis. I simulated the circuit and found the value of V0 to be 7.591 <72.0° V. However, I wasn't able to solve using mesh current method because of the current source in the middle.

The circuit diagram is attached. Any help is greatly appreciated. Thanks.

For two meshes containing the same current source take a path around the outside of the two meshes avoiding the current source - this is called a super mesh.

Thank you so much. Here is what I have so far. The final answer is different from what I had in PSPICE! Can someone please confirm my solution?

Thanks alot! I made the correction and got the same number Ic = 8.538 + j3.081.

but that wasn't the same as the result of your PSPICE right?
I know a different procedure from yours.

you obtained an equation IC-IB=12, from that you will get IB=IC-12. Try to substitute this equation from the other equation you get from the loops then omit the [0 -1 1 0 12] from the matrix.

I'm not quite sure if this will work but there's no harm in trying (if no high voltage is involved) :D
