A question about reciprocity theorem

  1. Nov 5, 2013 #1
    hello guys :))

    the question is : RUkFKY3.png

    in (a)
    IT= 10/[4k||8k+4k||4k]=2.14 mA

    but i can't calculate I so please guys help me i tried many times to get it but i couldn't :(

    thx guys !!

    I'm not following the equation you wrote for IT (I assume that is the I in the first figure?).

    Try re-drawing the circuit, and calculate the voltage of the shorting midpoint wire. Given that voltage, you can calculate the currents in the different legs of the circuit, which will give you I.
