AI Thread Summary
The user is experiencing discrepancies between their calculations and PSpice results while attempting to solve a voltage problem from a textbook. They are also seeking guidance on how to model a voltage with exponential decay, specifically in the form of 5e^(-t). The user has provided links to the problem and their attempt for reference. Feedback suggests that the polarity of the Vx sensing in the PSpice schematic may be incorrect. Clarification on these points is needed to ensure accurate voltage values of Vx and Vy.

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

correct?

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