Electrical Engineering Formulas: A Complete Reference of Essential Equations for Circuits, Machines, Power Systems, and Electronics
Master the equations that power electrical engineering-without searching through multiple textbooks.
Electrical Engineering Formulas is a comprehensive, practical reference designed to put the most important equations in electrical engineering at your fingertips.
Whether you are an engineering student, practicing electrical engineer, technician, researcher, or technical professional, this book provides a clear and organized collection of essential formulas for solving problems, checking calculations, reviewing concepts, and supporting real-world engineering work.
Rather than focusing on lengthy derivations, this reference emphasizes what engineers often need most: the correct equation, the meaning of every variable, the applicable units, and the conditions required to use the formula properly.
Inside, you will find formulas and relationships covering:
Electrical units, Ohm's law, energy, power, and efficiency
DC circuit analysis, including Kirchhoff's laws, mesh and nodal analysis, Th venin and Norton equivalents, superposition, and maximum power transfer
Capacitors, inductors, and transient circuits
AC circuits, phasors, impedance, resonance, and admittance
Real, reactive, apparent, and complex power
Power factor and power-factor correction
Balanced three-phase electrical systems
Magnetic circuits and electromagnetic principles
Transformers, including equivalent circuits, testing, regulation, and efficiency
DC motors and generators
Induction and synchronous machines
Transmission lines, per-unit calculations, fault analysis, and power-flow relationships
Diodes, BJTs, MOSFETs, and semiconductor fundamentals
Operational amplifiers and analog circuits
Rectifiers, converters, inverters, PWM, and power electronics
Fourier and Laplace transforms, filters, feedback, and control-system fundamentals
Electrical measurements, instrumentation, sensors, ADCs, and DACs
Electric heating, illumination, batteries, and electrochemistry
Digital electronics, Boolean algebra, timing, logic levels, and fan-out
Physical constants, conductor data, mathematical identities, symbols, and engineering reference material
Each section is structured for fast lookup and practical application, making it easier to move from a problem to the equation you need without wasting time searching through pages of theory.
The book also highlights important distinctions that frequently cause calculation errors, including RMS versus peak quantities, line versus phase values, real versus reactive power, sign conventions, operating assumptions, and formula validity conditions.
A Valuable Reference for:Engineering students preparing for coursework and examinations
Practicing electrical engineers performing calculations and design checks
Technicians and technologists working with electrical systems
Researchers and academics who need a convenient equation reference
Anyone who wants a dependable collection of electrical engineering formulas in one place
From basic circuit relationships to machines, power systems, electronics, signals, and control, Electrical Engineering Formulas brings together the equations that electrical engineers use again and again.
Keep the formulas you need within reach. Calculate faster. Verify your work. Solve with confidence.
