APR 191 Electrical Theory 2

Second course of a two-term sequence in electrical theory. This course covers basic AC circuits and components, right triangle mathematics, RLC circuits, filters, and resonant circuits and RL/RC transient circuits. In the lab students will build and troubleshoot basic AC circuits using the oscilloscope, function generator, and DMM. May be offered Distance Learning.

Prerequisite

ET 129 OR APR 190 

Course Learning Outcomes

7. Recognize the basic types of common transformers and perform power, voltage and current calculations on both the primary and secondary sides of the transformer
8. Perform AC reactance calculations for capacitors and inductors
9. Demonstrate a working knowledge of trigonometry in the study of AC reactive components and their phase angles
10. Analyze RC, RL and RLC circuits for individual currents, voltage and power drops and perform accurate impedance calculations for these circuits
