ISBN: 9798178479339 - electricity for electricians: the complete textbook of dc and ac circuits, motors, transformers and wiring principles (5 Ergebnisse)

Taschenbuch. Zustand: Neu. Neuware - Electricity for Electricians is a structured theory textbook for apprentices, classroom learners, working electricians refreshing their fundamentals, and candidates preparing for the theory portion of journeyman or master licensing examinations. Starting with electrical safety and assuming no prior electrical knowledge beyond high-school algebra, the book develops the subject in the order an apprentice needs it. The twenty chapters move from charge, current, voltage and resistance into Ohm's law, power, energy, series and parallel circuits, Kirchhoff's laws and circuit analysis. From there, the reader works through conductor resistance and voltage drop, batteries, magnetism, AC waveforms, RMS values, inductance, capacitance, impedance, resonance, power factor and three-phase wye and delta systems. The later sections apply that foundation to transformers, generators, DC motors, AC induction and synchronous motors, contactors, starters, overloads and control circuits. Grounding, bonding and overcurrent protection are explained from the behavior of fault current, while the final chapter connects test instruments, measurement categories, true-RMS readings, insulation-resistance testing and systematic fault isolation. Each chapter is designed for active study: - Learning objectives define the skills and concepts to master.- Worked examples show the given data, formula, units, substitution and final result.- On the Job sections connect theory to realistic service and troubleshooting situations.- Safety Alerts and Common Errors identify dangerous assumptions and frequent mistakes.- A field procedure models a supervised test or measurement and ends with an acceptance criterion.>The reference section keeps essential material within reach: a glossary, formula and conversion reference, resistor color code and standard values, conductor size and resistance tables, a motor and transformer formula card, answers to all chapter review questions, acronyms and an index. Use this book as a classroom companion, an apprenticeship theory text, a calculation refresher or a foundation for electrical exam study. It focuses on the principles behind the work so that formulas, machine behavior, protection and measurements make sense together. It is not a code-lookup manual and does not reproduce code tables, conduit-fill rules, box-fill rules or service-load calculations.Disclaimer: This book is for education and reference only. It does not qualify anyone to perform electrical work or replace a structured apprenticeship, supervised hands-on training, licensing, manufacturer instructions, or the codes, regulations, safety programs, lockout/tagout procedures and permits in force where the work is performed.…
