This document outlines the steps for Lab 8 of the ELEC 101 course. The lab covers schematic symbols for common electrical components like capacitors, resistors, and transformers. It also covers simulations of RC circuits to analyze the critical frequency, using a parametric sweep to vary capacitor values, and measuring the voltage transfer function of a transformer. The goal is for students to become familiar with component symbols and analyzing circuits using PSpice simulations.
