    hi,
    I was trying to solve this exercise using the mesh-current method.
    The question was, find V0 and Va using the mesh current method
    Attached is my attempt to solve it, but there seems to be something wrong since the Powers don't add up.
    Can someone please tell me what I'm doing wrong?

    I get your same values for Ia, Ib, and Ic. Looking at the polarity of the voltage across the current sources, it appears they both dissipate power just like resistors. However, review how you calculated the P.0,67 value of 384 W since all I got was 4 V at 12 A.
