In order to construct a building that will last into the future, a strong foundation is a prerequisite. The foundation is a part of the building that isn’t visible in the finished structure, but is essential in erecting a building that will have the necessary strength to endure.The math and basic electrical concepts of this unit are very similar to the foundation of a building. The concepts in this unit are the essential basics that you must understand, because you’ll build upon them as you study electrical circuits and systems. As your studies continue, you’ll find that a good foundation in electrical theory and math will help you understand why the NEC contains certain provisions. This unit includes math and electrical fundamentals. You’ll be amazed at how often your electrical studies return to the basics of this unit. Ohm’s law and the electrical formulas related to it are the foundation of all electrical circuits. Every student begins at a different level of understanding, and you may find this unit an easy review, or you may find it requires a high level of concentration. In any case, be certain that you fully understand the concepts of this unit and are able to successfully complete the questions at the end of the unit before going on. A solid foundation will help in your successful study of the rest of this textbook.
