    Friends,

    I trying to nodal analysis the AC circuit which has source of 60√90. Will the result always be 0 voltage on all nodes because cos 60 is 0? your expert advise please.

    Thanks,

    Naveed

    No. Go back and look at what amplitude and phase shift specifications mean -- namely, how you translate between that description and the full time domain description.

    Here are three equations of nodal analysis, which always come with 0 value. The complex number of AC source (60√90) is 0+60i

    V1(1-60i/(5-2i) +1/3+1/5i) - V2 (1/5i) = 0
    V2(1/5i+1/2i+1/1-2i) - V1 (1/5i) - V3(1/2-2i) = 0
    V3( 1/(2-2i)+1/3i) - V2 (i/2-2i) = 0
