## About the Book

This book covers Direct Current (DC) circuit theory and is broken up into three modules. Module 1 covers the basics for circuits that include DC sources (voltage or current) and resistors. Even though Module 1 is not very difficult, it forms the foundation for more complicated topics in modules 2 and 3 so it is important to have a firm grasp of all Module 1 topics before moving on. Module 2 covers more difficult problem solving techniques for circuits that include only DC sources and resistors. Module 3 introduces capacitors and inductors. These non-linear reactive components are analyzed in the transient and steady state regions in circuits with DC sources in Module 3. Also annexed is a two-page cheat sheet that ENGR 2431 students at University of Oklahoma can use for exams.

## About the Contributors

### Author

**Chad Davis** received his PhD from the University of Oklahoma in 2007. Since 2008 he has been a full-time member of the ECE faculty at OU. He holds a dual discipline (electrical & mechanical) professional engineering license in the state of Oklahoma. Prior to joining the OU-ECE faculty he worked in industry at Uponor, McElroy Manufacturing, Lucent, and Celestica. His work experience ranges from electromechanical system design to automation of manufacturing and test processes.

Dr. Davis is a licensed private pilot and performs research primarily in areas related to aviation. His current research at OU involves the design and development of a new GPS Ground Based Augmentation System utilizing feedback control and the design of instrumentation and data acquisition for navigational systems. Additionally, he serves as the ECE recruiting coordinator and one of the primary academic advisors for ECE students.
