ELECTRICAL ENGINEERING FUNDAMENTALS: Master Circuit Analysis, Ohm's Law, and AC/DC Theory with Step-by-Step Worked Examples
About this ebook
Most circuit textbooks hand you a formula, jump three lines of algebra, and print an answer you can't reproduce. That gap is where students lose this subject — not in the theory, but in the steps nobody bothered to write down.
Electrical Engineering Fundamentals closes it. More than 180 worked examples are solved line by line, with every substitution visible, every unit tracked, and every sign accounted for. Where a mistake is commonly made, the book names it and explains exactly why it happens — so you catch it in your own work before an exam does.
The eighteen chapters are built as a dependency chain, not a menu. You start with charge, current, voltage, and power, then move through Ohm's law and network reduction, nodal and mesh analysis, and the network theorems that collapse a complicated circuit into a simple equivalent. From there: capacitance and inductance, RC and RL transients, second-order response. Then alternating current — phasors, AC power and power factor, resonance and filters, three-phase systems. The final part puts it to work: magnetic circuits and transformers, rotating machines, semiconductors and rectifiers, transistors and amplifiers, measurement and instrumentation, and a full treatment of power distribution and electrical safety.
Inside this book:
181 worked examples with complete, step-by-step solutions
179 practice problems, every one with a worked answer key
20 precision figures — phasor geometry, hysteresis loops, torque–speed curves, device characteristics
Learning objectives opening every chapter and an equation summary closing it
Seven appendices: complex and phasor algebra, physical constants, standard component values and AWG ampacity tables, IEEE/ANSI schematic symbols with IEC equivalents, SI units and conversions, a differential equations refresher, and semiconductor device data
A full glossary, symbol list, and index for fast lookup
Written for: first-year engineering undergraduates working a circuits sequence; technicians and apprentices who want the theory behind the practice; mechanical, civil, and industrial engineers who need working command of electrical fundamentals; and self-taught learners studying without an instructor.
You need: algebra, basic trigonometry, and an idea of what a derivative is. Calculus and complex numbers are developed from the ground up where they're needed.
This is the explanation a good instructor would give you at the board — written down, in full, for every problem in the book.

About the author
Marcus D. Whitfield writes technical texts for students and self-teachers working through their first circuit sequence. His approach comes from a simple observation: most people who struggle with electrical engineering are not struggling with the concepts but with the steps between them — the substitution that was assumed, the unit that was quietly converted, the sign that changed without comment.
He writes for first-year undergraduates, apprentices and technicians who want the theory behind work they already perform, engineers crossing over from adjacent disciplines, and career-changers studying alone. Electrical Engineering Fundamentals is written for all four.
