Description: Now in its seventh edition, Practical Problems in Mathematics for Electricians contains 45 instructional units featuring updated materials, examples, and expanded mathematical operations for students and trainees of the electrical trade. Coverage begins with simple addition and subtraction of whole numbers and progresses through basic algebra and trigonometry, developing readers' awareness of electrical symbols, basic circuits, component terminology, and calculator use for success on the job. Word problems designed to encourage the use of logical deduction are just one of the hallmarks of this tried and true guidebook that provides the mathematical background students need to succeed in the electrical field. Explanations at the beginning of each unit foster a better understanding of the concepts being presented; while problems related to electricity help develop an appreciation for electrical terms and practices. Product Benefits: - A new unit on number systems has been added that examines the decimal, binary, octal, and hexadecimal number systems.
- Many new drawings and word problems feature multiple steps to exercise the ability of readers to reach logical conclusions.
- Opportunities to practice math principles in problems that are specifically designed for the electrical field are integrated throughout.
- Expansive coverage explores the mathematical units used in today?s scientific and engineering applications.
- Answers to odd numbered problems are given, and an all-inclusive appendix features basic mathematical operations, conversions, symbols, and terminology.
