Uses an electron-flow approach throughout, and incorporates mathematical concepts only when needed to understand the discussion. Covers everything from components, quantities and units to voltage, current and resistance; series circuits; magnetism and electromagnetism; phasors and complex numbers; capacitors; inductors; RC and RL circuits; circuit theorems, and more. Considers reactive circuits by circuit type as well as by component type. Integrates many TECH Tips (Technology Theory Into Practice) and PSpice Computer Analysis sections that apply theory learned to a practical activity using realistic circuit board and instrument graphics. Weaves worked examples and related exercises throughout to clarify basic concepts and illustrate procedures and troubleshooting techniques.
