Course Description from Catalog: Principles of electrical circuit analysis. Kirchhoff's laws, equivalent circuits, dependent sources, node and mesh analyses, signals, RLC components. Introductory circuits and operational amplifier circuits as examples.

Topics: Selected from chapters 1-6, 8, 9 of textbook.

  • Ohm's Law for resistors
  • Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL)
  • Independent and dependent sources
  • Instantaneous power and passive sign convention
  • Nodal analysis and mesh analysis
  • Operational amplifier (op amp) with ideal assumptions
  • Thevenin's Theorem and Norton's Theorem
  • Voltage-current relationships for inductors and capacitors
  • Analysis of RLC circuits to find differential equations
  • Solution of differential equations using classical (time-domain) techniques
  • AC (sinusoidal steady-state) analysis
  • AC power

Course Outcomes: Students will be able to

  1. analyze circuits by applying voltage-current relationships for elements and basic laws such that algebraic equations or differential equations are found to relate voltages and/or currents to inputs/sources (constant, sinusoidal, switched, ...);
  2. solve systems of linear equations and linear differential equations using classical (time-domain) techniques;
  3. recognize when a circuit may be analyzed using AC analysis, represent the circuit appropriately in the frequency-domain, and analyze the circuit such that voltages and currents are determined; and
  4. calculate instantaneous power and/or AC power absorbed by an element.
