Descrição do livro

Electricity is invisible, and that is exactly why it is so easy to learn the formulas without ever understanding the circuit.
Most people who set out to learn electrical engineering stop in the first few weeks — not because the subject is beyond them, but because the explanations assume the steps they are missing. A formula appears with no derivation. A worked example jumps three lines of algebra. Notation changes from one source to the next. And the moment a circuit holds two sources instead of one, the familiar rules quietly stop working.This book takes the whole subject in one deliberate sequence, from what electric charge is to how an instrument reports a measurement. Notation is fixed in the first chapter and used unchanged to the last. Every relationship that matters is derived rather than quoted, and every chapter ends with problems that show whether the idea took hold: 282 worked examples solved step by step and 342 practice problems with a complete answer key, across fourteen chapters.What you will be able to do:

  • Work confidently with charge, current, voltage, energy and power, including the sign conventions and unit prefixes that trip up most beginners
  • Choose the right method for a circuit — series and parallel reduction, divider rules, node voltages, loop currents, equivalent sources or superposition — instead of forcing one technique onto every problem
  • Predict what circuits that store energy actually do: time constants, charging and discharging, damping regimes and overshoot
  • Handle alternating current properly — RMS values, phasors, impedance, real and reactive power, power factor correction and resonance — and analyse transformers and AC power distribution
  • Analyse diodes, rectifiers, regulators, transistor switches, amplifier stages and operational-amplifier circuits, and see where a real device departs from its ideal model
  • Simplify logic and build combinational and sequential circuits, from gates and adders to flip-flops, counters and state machines
  • Understand motors and generators — torque, speed, efficiency, control — and measure safely, allowing for shock physiology, grounding, protective devices and meter loading

Practical judgement is developed alongside the mathematics: tolerance stacking and worst-case values, thermal limits and bias stability, non-sinusoidal waveforms, oscilloscope and multimeter behaviour, and the reasoning behind grounding, bonding, fusing and fault protection. The back matter adds a glossary of every key term and a consolidated list of symbols that flags where one letter carries more than one meaning.

It is written for self-taught beginners, students starting an engineering or technical programme, apprentices and technicians who want the theory behind their daily work, and makers who would rather understand a circuit than copy one. Comfort with algebra and a first acquaintance with derivatives is enough to follow every derivation. It is an educational text, not a substitute for a licensed professional on design or installation work.

Start at the first principle and work forward. Open this book, follow the derivations, solve the problems, and begin reading circuits with understanding instead of guesswork.
