Hello,

I'm new to PSPICE and it seems I need a little help. I have OrCAD 10.
I'm trying to simply put a resistor in series with a capacitor and
connect a 10V power supply (VDC). I set a voltage tester between the
resistor and capacitor and when I run a transient alanysis, I get a
straight line at 10V. No matter what time values, no matter what
values I use for the resistor and capacitor, I ALWAYS get a straight
line.

I changed the VDC to a VSTIM and set up a square wave. Sure enough, on
each pulse, I see a curved rise and a curved fall. Why don't I see a
curved rise at the start of the simulation with VDC?? I don't want to
use a square wave generator, I just want a simple voltage source like a
battery. What is going on??

Any help is appreciated! Thanks!

I would use the IC ("Initial Condition") parameter available in the
capacitor property editor field. Just set it to "0". Otherwise it
starts to simulate the situation departing from the bias calculation
situation.
