Available on video or CD-ROM, this series of 17 videos correlates directly to Delmar's Standard Textbook of Electricity and serves as a perfect introduction (or supplement) to information covered in the book. The first set of 9 tapes correlates to the first half of the text, where viewers will learn the basics of DC and AC theory. This includes topics such as Ohm’s Law, batteries, inductance, and resistance. The second set, is broken into two sets of four tapes. The first four tapes illustrate the construction of the machines, their principles of operation, and how to properly connect them to a circuit. The second four tapes bring single-phase transformers and machines to life, providing detailed explanations of construction of the machines, principles of their operation, and their connections or “hook ups”. Safety is strongly emphasized in each video and special attention is given to explaining all electrical formulas and calculations clearly and in detail. In addition, consistent, easy-to-understand explanations and examples are used to explain where and how each type of machine might be used, while helpful graphics and professional-quality animations have been thoughtfully designed to provide tomorrow's technicians and technologists with a foundation in order to study more complex electricity and electronic concepts.
