Electric Circuits

This page describes the format of the second section of the EEGR2053 Electric Circuits class that was taught in the spring of 2019 at LeTourneau University. The class has covered resistive circuit analysis, steady-state sinusoidal analysis, the transient response of first-order RL and RC circuits, power, three-phase circuits, and an introduction to transformers. Related classes are EEGR2051 Circuits and Measurements Lab and EEGR2163 Advanced Circuits. The circuit topics that are not covered in Electric Circuits (frequency response, circuit analysis based on the Laplace transform, Fourier analysis, ...) are taught in Advanced Circuits.

Textbook: Circuit Analysis and Design, by F.T. Ulaby, M.M. Maharbiz, and C.M. Furse, Michigan Publishing, 2018.

Homework: 38 homework sets were assigned.
