Homework Help: Help with PSpice/OrCAD Voltage Dependent Sources

  1. Apr 29, 2010 #1
    1. Right now I am trying to recreate a problem from the book with pspice however, the math I have performed on the problem is not the same as what pspice is telling me.

    2. Also how do I represent a voltage that has exponential decay with time (such as 5e^(-t))

    3.here is the problem(finding Vy and Vx) http://i23.photobucket.com/albums/b400/Insanity_is_me/PSPICE/1B.jpg

    and here is my attempt http://i23.photobucket.com/albums/b400/Insanity_is_me/PSPICE/attempt1b.jpg

    ANY help would be greatly appreciated....by my math the voltages should be Vx=8v and Vy=10v

    Looks like the polarity of the Vx sensing is backwards in your PSpice schematic?
