Infinite Ladder Network

  1. Aug 3, 2004 #1
    The http://www.his.com/~mhtesler/Ladder[/PLAIN] [Broken] Network4.jpg]network shown (<—click on this link) is an infinite ladder of resistances (i.e., the “L-section” pattern of Rs and Rp resistances repeats indefinitely towards the right).


    Rs = 1 ohm


    Rp = 6 ohms.

    What is the input resistance R (i.e., the resistance between terminals A and B)?

    R(A-B) = 3 ohms ?

    I agree with Gokul

    it is an elegant problem

    [tex]x = 1 + \frac{1}{1/6 + 1/x}[/tex]
