Catalog Course Description

Focuses on D.C. single- and multi-source circuitry with the application of loop, node, and Thevenin’s theorem. Also covers A.C. reactive circuits using both phasors and complex numbers for determining reactance, impedance, and power factor. Laboratory activities.

Core Course Learning Objectives (Separated)
1. Solve D.C. single source series, parallel and combination circuitry.
2. Solve A.C. single source series, and parallel circuitry involving resistive, inductive, and capacitive components.
3. Analyze A.C. reactive circuit conditions, to calculate for impedance values, and to determine phase relationships using phasors (vectors).
4. Demonstrate an understanding of complex numbers (j-operator) as it would apply to A.C. reactive circuit analysis.
5. Solve A.C. reactive circuit conditions using both polar and rectangular forms of analysis.
6. Determine the real, reactive, and apparent power values for A.C. circuit conditions.
7. Demonstrate an understanding of the resulting effects of the power factor and when necessary correct the power factor condition for optimum circuit efficiency.
8. Solve D.C. multi-source circuits using Thevenin’s theorem and to simplify the circuitry to the Thevenin’s equivalent network.

### Assessment and Requirements

1. Unit and chapter tests given throughout the semester.  Tests represent 50 percent of the course grade.
2. Informal and Formal laboratory activities and performance exercises in which students demonstrate an understanding of assigned circuits.  Formal laboratory activities are submitted as a written report and represents 25 percent of the course grade.
3. Final exam in which common questions are asked covering the units and topics presented throughout the semester.  The final exam is worth 25 percent of the course grade.
