An essential resource for both students and teachers alike, this DC Electrical Circuits Workbook contains over 500 problems taken from the author's DC Electrical Circuit Analysis text. Each chapter begins with an overview of the relevant theory and includes exercises focused on specific kinds of circuit problems such as Analysis, Design, Challenge and Computer Simulation. An Appendix offers the answers to the odd-numbered Analysis and Design exercises. Chapter topics include fundamentals for current, voltage, energy, power and resistor color code; series, parallel, and series-parallel resistive circuits using either voltage or current sources; analysis techniques such as superposition, source conversions, mesh analysis, nodal analysis, Thévenin's and Norton's theorems, and delta-wye conversions; plus dependent sources, and an introduction to capacitors and inductors. RL and RC circuits are included for DC initial and steady state response along with transient response. This is the print version of the on-line OER.
