Triangular Resistance Network

  1. Apr 25, 2015 #1
    1. The problem statement, all variables and given/known data
    Assuming R = R' in the network shown above, determine the net resistance between the points a and c. Express your answer as a number times R.
    b. Assuming R = R', determine the net resistance between the points a and b.
    c. Now suppose R' = 2.5R, and find the net resistance between points a and b.

    2. Relevant equations
    Req=R1+R2+R3
    For resistors in series

    1/Req= 1/R1+1/R2+1/R3
    For resistors in parallel
    3. The attempt at a solution
    I tried to redraw the circuit, but I'm not sure I did it right. Also, I would think that the resistance would just be R because there is only one resistor from a to c, but that seems too easy. Any help would be appreciated.

    The answer is not R as there is certainly more than one path from a to c. You really should show at least some of your attempt(s) even if they didn't pan out, and not just say that you tried this or that. We need to see how you've approached the problem in order to know how best to help.
