Alternating Current is a course designed to familiarize participants with how alternating current (AC) circuits work, and how voltage and current can change depending on the load, the source, and how the load and source are connected together. After completing this course, participants should be able to determine current and voltage values for an AC sine wave; explain how resistance, inductance, and capacitance affect AC circuits; explain how to calculate power in AC circuits and how to adjust power by correctly selecting and sizing circuit components; and describe the construction, operation, and use of various types of transformers.
