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
