What’s so great about this? 1. Circuit analysis In many situations, circuits can be analyzed much more easily by exploiting source equivalence 2. Modeling Many complex circuits can be described by an ideal source and resistor (e.g. sensor, radio antenna, …) Examples EE 40 Lecture 5: Source Transforms 6
