Chapter 3 Introduction

This chapter will expose you to different electrical laws and theories that will help you to understand and interpret Digital Multimeter (DMM) readings and electrical wiring diagrams/schematics.   Mastering these laws and theories will help you proof read or verify the correctness of written diagnostic routines as you follow them and the schematic at the same time.  The electrical theories and circuit laws of Georg Simon Ohm and Gustav Robert Kirchhoff have a huge impact on automotive electronics.  More information on these men's work is in this chapter.
