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.

**Lectures:** The class had 40 lectures of 55 minutes each and two midterm tests. The material was structured as follows:

- Current and voltage
