PSpice question: How do I plot equivalent impedance v. frequency?

Click For Summary
SUMMARY

The discussion focuses on plotting equivalent impedance (Zeq) versus frequency in PSpice while in AC mode. The user initially struggled with writing trace expressions for Zeq but later clarified that the expression should be based on voltage (V) over current (I). The modeling of Zeq using a resistor and inductor in series with an AC voltage source was confirmed, but the user sought further guidance on directly modeling from the original circuit and addressing the imaginary component of impedance.

PREREQUISITES
  • Understanding of PSpice simulation software
  • Knowledge of AC circuit analysis
  • Familiarity with impedance concepts, including real and imaginary components
  • Experience with trace expressions in PSpice
NEXT STEPS
  • Research how to use PSpice to plot frequency response of circuits
  • Learn about the calculation of equivalent impedance in AC circuits
  • Explore the use of trace expressions in PSpice for complex calculations
  • Study the impact of inductors and resistors on impedance in AC analysis
USEFUL FOR

Electrical engineers, circuit designers, and students working with PSpice who need to analyze and visualize equivalent impedance in AC circuits.

How do I plot equivalent impedance v. frequency? I'm already in AC mode so the frequency is taken care of, but I keep trying to manually write trace expressions for zeq and nothing is working. any tips?

EDIT: What does the trace expression IP(some element) mean? I think its related.
EDIT2: I think i got it, I'm just V/I in the trace. I think its working how I want.

EDIT 3: Not quite, let me provide a few more details. I've modeled the Zeq by a resistor and an inductor in series with an AC voltage source. Is this the way I should model it? Or is there a way I can do it directly from the original circuit. If so, from there how should I plot the Zeq v. freq? I'm especially having trouble thinking about the imaginary part.
