1. Introduction

The ability to describe how something is done is vital in technical fields. Unit 4c covered this topic from the point of view of an instructor explaining a process to a trainee orally while demonstrating the individual steps. Processes and procedures, however, can also be described more formally in writing. This is what Unit 5a focuses on first within the context of soldering and later while discussing electrolysis, which seems to be one of the most important processes in electrical engineering.
