Book Preface

The Handbook o[ Electronics Formulas, Symbols and Definitions has been compiled for engineers, technicians, armed forces personnel, commercial operators, students, hobbyists, and all others who have some knowledge of electronic terms, symbols, and theory.

The author’s intention has been to provide: A small, light reference book that may be easily carried in an attache case or kept in a desk drawer for easy access. A source for the majority of all electronic formulas, symbols, and defmitions needed or desired for today’s passive and active analog circuit technology.

A format in which a desired formula may be located almost instantly without the use of an index, in the desired transposition, and in sufficiently parenthesized linear form for direct use with any scientific calculator. Sufficient information, alternate methods, approximations, schematic diagrams, and/or footnotes in such a manner so that technicians and hobbyists may unl!erstand and use the majority of the formulas, and that is acceptable and equally useful to engineers and others very knowledgeable in the field.

INTRODUCTION

All formulas in this Handbook use only the basic units of all terms. It is especially easy in this age of scientific calculators to convert to and from basic units.

Formulas in all sections are listed alphabetically by symbol with the exception of applicable passive circuit symbols, where, for a given resultant, all series circuit formulas are listed first, followed by parallel and complex circuit formulas. If the symbol for an electronic term is unknown, a liberally cross-referenced listing of electronic terms and their corresponding symbols may be found in the appendix.

Symbols of all reactive magnitude terms in formulas have been consistently given the signs conventionally associated with them to maintain capacitive or inductive identity. In rectangular quantities, this also allows identification of the complex number as representing a series equivalent impedance/ voltage or a parallel equivalent admittance/current. To prevent possible confusion, all symbols representing vector quantities in polar or rectangular form have been printed in boldface.

A number of formulas have the potential to develop a zero divisor. Conventional mathematics prohibits a division by zero, and calculators will overflow if this is attempted. However, formulas noted <a> allow the manual conversion of the reciprocal of zero to infinity and the reciprocal of infmity to zero. Division by zero in formulas noted ® is prohibited.

Textbooks conventionally use italic (slanted) type for quantity symbols and roman (upright) type for unit symbols. However, this Handbook follows the example of almost all technical manuals, using roman type for both quantity and unit symbols.
