Back To Basics

Welcome to Module 4, which is about the Transformer.

In this module you will begin to appreciate how the topics discussed in previous modules form the critical foundation for new topics. Topics from Modules 2 and 3–such as electromagnetism, power, utility systems, and electrical distribution–all contribute to a more solid understanding of transformers.

Like the other modules in this series, this one presents small, manageable sections of new material followed by a series of questions about that material. Study the material carefully then answer the questions without referring back to what you’ve just read. You are the best judge of how well you grasp the material. Review material as often as you think necessary. The most important thing is establishing a solid foundation to build on as you move from topic to topic and module to module.
