Author: Stephen Herman 
Ninth Edition 
PRACTICAL PROBLEMS
IN MATHEMATICS FOR ELECTRICIANS, 9E will give readers the math
skills they need to succeed in the electrical trade.
It introduces them to the important math
principles through problems designed for the electrical profession
and offers them an excellent opportunity to develop and practice
problemsolving skills while at the same time providing a valuable
review of electrical terminology.
This new edition uses the same straightforward
writing style and simple, stepbystep explanations that made
previous editions so readerfriendly. It minimizes theory and
emphasizes problem solving techniques and practice problems.
This new edition also 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
concludes with trigonometry.
Practical problems with realworld scenarios
from the electrical field are used throughout, allowing readers to
apply key mathematical concepts while 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:
 This
edition's enhanced; numerous diagrams, charts, and other
illustrations offer more dimensional images to help
students more clearly visualize how key math concepts
apply to the trade.
 Multistep
word problems encourage your students to apply what they
have learned, allowing them to be active participants in
the learning process.
 Proven,
effective stepbystep examples throughout this edition
encourage students to follow each procedure closely,
ensuring their comprehension as they progress throughout
the text.
NEW to this
Edition:
 This edition's threedimensional
enhanced illustrations help students clearly visualize
how key mathematical concepts apply to the trade.
 To maximize the tools available
on the job, new detailed coverage of calculator usage
for solving problems has been added throughout the text
as applicable.
