AC Sweep Analysis of RLC Circuit


Using this parallel RLC circuit, run an .ac sweep from 1kHz to 100kHz and plot a graph of the output voltage across R2
Here’s the AC sweep plot of |V(out)| across R2 from 1 kHz to 100 kHz:

AC Sweep: Magnitude of V_out across R2

Key observations:
  • Low-frequency attenuation (~0.01 at 1 kHz)
  • Peak magnitude (~0.12) around 10 kHz (resonance)
  • High-frequency roll-off back toward ~0.01 at 100 kHz
