    thanks alot for the answer, i just wonder how do you get resistance equal 12 ohm ? . Follow your picture which u drawn If i add resistor 1,2,3 to gether by parallel then it equal .333 ohm,the same with resistor 4,5,6 i have .333 ohm. For the branh with 6 resistor i have 6 ohm if add them togehter bye series: .333 +.333 + 6 = 6.666 ohm than it isn't equal 12 ohm like you said .i am not sure that i was right or wrong , if i did wrong just let me know. thanks

    yup sorry my calculations are wrong
    the resistors of 3 add to give .3333
    and the 6 resistor set gives .1667
    so the net comes to .1667+.6666=.83333 ohms
    pls check my calc again and let me know

    so the current Is = 1/.83333= 1.2A ? -->i think this may be the final answer
