Click For Summary
The discussion revolves around calculating current (I) in a circuit using the reciprocity theorem. The user initially calculates IT as 2.14 mA but struggles to find I. A suggestion is made to redraw the circuit and determine the voltage at the shorting midpoint wire. This voltage can then be used to calculate the currents in the circuit's different branches, leading to the solution for I. The conversation emphasizes the importance of visualizing the circuit for accurate calculations.

bibo_dvd said:hello guys
the question is :
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.

Homework EquationsThe Attempt at a Solution
I assumed there to be two supernodes. The first one was between V1 and V2. The second supernode was between V2 and V3.
This is what i tried and i am not getting the right answers. Please can someone help me out! Apologies for the turned pictures. The actual answers are V1 =7.608v , V2 =-17.39v , V3 = 1.6305v
