Open: AC Electrical Circuit Analysis, A Practical Approach

Preface:

Welcome to the AC Electrical Circuit Analysis, an open educational resource (OER). The goal of this text is to introduce the theory and practical application of analysis of AC electrical circuits. It assumes familiarity with DC circuit analysis. If you have not studied DC circuit analysis, it is strongly recommended that you read the companion text, DC Electrical Circuit Analysis before continuing.
