    in two loops at the top, when different currents float in different loops, can they change their current or , while one of them is increasing, is other one decreasing..? i could not decide if the question is so easy or hard.

    As long as the terminals a-b are open circuited, no current can flow outside of the loops -- there's nowhere for it to flow to. A complete, closed circuit is required for current to flow.

    ah, okey , then i apply Kircoff Voltage Rule on the each loops and find V1 , v2 and the last one which is already 15 and add them up in terms of their sign, and the result thanks for help gneill
