Electrical Engineering Reference Manual

Electrical Engineering Reference Manual for the PE Exam

5th Edition, by Raymond B. Yarbrough--A Summary

Introduction. This manual is a review of topics in electrical engineering, meant to be reviewed--rather formally, possibly in a class-room setting--by persons working in the field 5 to 7 years or more after passing their Fundamentals of Engineering or Engineer-in-Training (EIT) exam. This review of problems is intended to prepare the "student" (a working engineer, likely rusty in applications of various theoretical aspects) for an 8-hour, open-book Professional Engineer's (PE) exam, qualifying him or her for a (single) state license in Electrical Engineering.

The manual contains seventeen chapters, 5 of which cover important review topics, such as mathematics and systems of units, that are not specifically covered on PE exams but which subsume a number of problems that are covered. All chapters include: mathematics; linear circuit analysis; waveforms, power, and measurements; time and frequency response; power systems; transmission lines; rotating machines; fundamental semiconductor circuits; amplifier applications; waveshaping, logic, and data conversion; digital logic; control systems; illumination and the National Electric Code; economic analyses; systems of units; management theories; and engineering licensing. Page-only citations herein are clearly to this manual (Yarbrough, 1997).

Kirchhoff's voltage and current laws appear at p. 6-11. 7. Rotating Machines. Topics reviewed are: fundamentals of DC machines (pp. 7-2 and -3), DC generators (pp. 7-3 to -7), DC motors (pp. 7-7 to -12), induction motors (pp. 7-12 to -18), and synchronous machines (pp. 7-18 to -25). Their object is to produce torque in a shaft and thereby to perform useful work. The review of fundamentals defines generated voltage (EG), rated shaft speed (OR), and field flux (F)(p. 7-2). The proportionality among the variables, KV = EG/F OR, is almost equal to the number of series turns on the rotor (p. 7-2). In consistent units, Power = EGIA (armature current), and P = TOR, where T = torque (usually in ft-lb) (p. 7-2). Example 7.1 relates voltage, power, rotation speed, armature resistance loss (IA2Ra), horsepower , and field current (IF)(p. 7-3). Though steps are omitted, Examples 7.2 and 7.3 show magnetization curves being used to deduce armature and field resistances, generated voltage, fi
