Product Description:
Understanding the theory and application of electrical concepts is necessary for a successful career in the electrical field specifically in industrial maintenance and installation, and this newly revised, full color text delivers! Delmar's Standard Textbook of Electricity, Fourth Edition trains aspiring electricians by blending concepts relating to electrical theory with practical 'how to' information that prepares readers for situations commonly encountered on the job. This revision retains all the hallmarks of our market-leading prior editions, but displays enhancements such as more practical application problems. Topics span the major aspects of the electrical field including direct and alternating current circuits, basic theory, transformers, generators, and motors. This new edition has been organized so that all relevant information is located within a given chapter which allows for flexibility to access and cover topics in any order making this text an indispensable resource.

Rating : - Needs better identifying of formulas and more practice problems
This is a very poor book and an even poorer textbook. Formulas are not identified well enough. There are very few problems to practice on and the 10 or so Review Questions at the end of each Unit are of little assistance. If there were more practice problems with each formula, then the text would be infinitely better. Electronics & electricity both require a lot of math. The author should consider that there are numerous formulas to be memorized in a short period of time. In our case, we have 5 weeks to cover the AC section. To make things worse it is difficult to locate formulas when looking back through the text. The Appendix that has the formulas should not assume that everyone can remember all of the formulas or when to use every formula.

We used the 4th edition and the section on Basics of Alternating Current required trig tables to do some problems. In the 4th edition the trig table in "Appendix A or B" was absent even though on page 450 it was referenced. Furthermore, in some 4th editions the Solution box for this problem on page 450 had two sentences and some other 4th edition texts did not have this wording. (The sentences said: "Note: 0.151 is the sine of the angle, not the angle. To find the angle that corresponds to a sine of 0.151, use the trigonometric tables located in Appendices A and B or a scientific calculator.)

Perhaps a better text for AC basic classes would be Herman's other text titled Alternating Current Fundamentals. It requires more advanced math, but is better written and the formulas are better presented.

In our class we have a software program that has many of the math problems. At least they can be "played with" like one does with in advanced math classes to understand the formulas and to check your answers.

Again, identifying how to use each formula and adding practice problems for each formula would greatly improve this text.
