Lecture (L2-3) Equivalent Circuits

Introduction:

Equivalent circuits are used to simplify analysis of many types of systems, and they often help us understand how a particular part of a circuit is working.  This lecture also covers series and parallel circuits for resistance, conductance, voltage, and current. This analysis is the 'bread and butter' of ECE, and is used all the time.  Voltage and current dividers are also discussed. These are also constantly used.
