This new edition of Practical Problems in Mathematics for Electricians will help you gain the math skills you need to succeed in the electrical trade. Using the same straightforward writing style and simple, step-by-step explanations that made previous editions so reader-friendly, the eighth edition includes updated illustrations and information for a better learning experience than ever before! The book begins with basic arithmetic and then, once these basic topics have been mastered, progresses to algebra and then trigonometry.
Practical problems with real-world scenarios from the electrical field are used throughout, allowing you to apply key mathematical concepts at the same time as you are developing an awareness of basic electrical terms and practices. This is the perfect resource for anyone entering the electrical industry, or simply looking to brush up on the necessary math.
Features:
- Diagrams, charts, and other illustrations have been updated to help you visualize key concepts.
- Multi-step word problems encourage you to apply what you have learned, allowing you to be an active participant in the learning process.
- Step-by-step examples ensure a clear understanding of each step is established before moving on to the next one.
From the Preface
In order to succeed in the electrical field, one must have a substantial background in mathematics. The eighth edition of Practical Problems in Mathematics for Electricians has been written to provide beginning students with these needed skills. The text starts with basic arithmetic and progresses through algebra and trigonometry. The explanations at the beginning of each unit provide the student with a better understanding of the concepts being presented. Most of the problems are word problems designed to encourage the student to use logical deduction to arrive at an answer. Many of these word problems are multistepped. Problems related to the electrical field are used throughout the text to help students understand electrical terms and practices.
In addition, an awareness of electrical symbols, basic circuits, component terminology, and calculator use is developed through the text. The answers to odd-numbered problems are provided in the back of the text along with a complete appendix.
