This document discusses solving RLC series parallel circuits using Simulink. It introduces Kirchhoff's voltage law and differentiating the voltage equations to express the RLC response in general form. It provides a Simulink model for a series RLC circuit and instructs the reader to change component values and make a parallel RLC model. It also introduces the SimPowerSystems library for modeling electrical systems in Simulink and lists some commonly used blocks with an example circuit.
