    The guidelines clearly prohibit us providing complete solutions or helping you until you have posted an attempted solution, or at the very least, your thoughts.

    I appreciate that you are a compute engineer, but surely in your course you must have had to attend at least an introductory course on circuitry.

    I have read about superposition theorem and i know serial & parallel connetcions

    for SP theorem, i should shortcircut the other connetcions and do the calculation, at the end sum everything together, but my question is,

    do i need to conider the loops,
    if i close v2 & v3 and find total currecnt using v1 only. where should i strat from .

    if you can give me a solution with V1 only, il try myself for the rest.

    please guide me, im not asking for spoon feeding, please give me a guideleine....

    When you short-circuit two of the sources, all you have is one source and several resistors. You can use loop or node analysis or you can use your knowledge of series and parallel connections and calculate the resulting resistence. From that you can calculate the current delivered by the source and work backwords to calculate the current in R9.
