This document provides an overview of using PSPICE, a circuit simulation software, to simulate electrical circuits. It discusses that PSPICE was developed based on SPICE and is used to model circuit behavior before physical implementation. It then describes how to install PSPICE, prepare a circuit for simulation by entering components and settings, and run different types of analyses like DC, transient, and AC simulations. An example of simulating a simple clipper circuit is also provided.
