Electric Circuits

Now readers can master the fundamentals of electric circuits with Kang’s ELECTRIC CIRCUITS. Readers learn the basics of electric circuits with common design practices and simulations as the book present clear step-by-step examples, practical exercises, and problems. Each chapter includes several examples and problems related to circuit design, with answers to odd-numbered questions so learners can further prepare themselves with self-guided study and practice. ELECTRIC CIRCUITS covers everything from DC circuits and AC circuits to Laplace transformed circuits. MATLAB scripts for certain examples give readers an alternate method to solve circuit problems, check answers, and reduce laborious derivations and calculations. This edition also provides PSpice and Simulink examples to demonstrate electric circuit simulations. Electric Circuits 1st Edition 1e by James S.
