Finding configuration of resistors

  1. Mar 10, 2009 #1
    1. The problem statement, all variables and given/known data

    You are given a black box with three terminals, as shown below. The box is known to contain five 1-ohm resistors.


    (d rectangle cannot b seen but jus imagine d rectange wid d terminal A on left side and B and C on d right side)
    Using an ohm-meter, you measure the resistance between the terminals to be the following:
    A - B: 1.5 ohms
    B - C: 3 ohms
    A - C: 2.5 ohms

    Determine the configuration of the five resistors inside the box.

    2. Relevant equations

    i jus noe d basic eqns 4 solvin resistances in !! n series.

    3. The attempt at a solution

    resistances b/w B and C r 3 resistances in series and b/w A and B could like 1 in series n 2 in parallel,b/w Aand C could be 2 in series n 2 in parallel but d total resistances r jus 5. help !!!!!
