Course Description

Sinusoidal steady-state analysis, phasors, AC power, three-phase circuits, frequency response, filters, and Laplace transform circuit analysis. EE 202 continues the study of electric circuits, transitioning from basic resistive and transient circuits to alternating current (AC) steady-state network analysis and advanced frequency-domain techniques. Students master phasor algebra, complex power calculations, balanced three-phase distribution systems, and magnetically coupled coils. The second half of the course examines network frequency response, active and passive filter design, Bode magnitude and phase plots, and complete transient and steady-state circuit analysis using the Laplace transform.

Prerequisites

EE 201; MATH 340 (prior or concurrent).

Measurable Student Learning Outcomes

Upon successful completion of EE 202, students will be able to:

1. Analyze Sinusoidal Steady-State Networks: Transform time-domain sinusoidal circuits into phasor domain representations and apply nodal, mesh, and Thévenin/Norton network reduction techniques.
2. Calculate AC Power and Power Factor: Compute instantaneous, real, reactive, and complex power, calculate power factors, and size capacitor banks for power factor correction in inductive loads.
3. Solve Balanced Three-Phase Systems: Analyze balanced three-phase Wye-Wye and Wye-Delta circuits, calculating line and phase voltages, currents, and total real and reactive power.
4. Design and Characterize Filters: Determine network transfer functions, sketch asymptotic Bode diagrams, calculate resonance frequencies and quality factors, and design passive and active filtering circuits.
5. Apply Laplace Transforms to Circuit Dynamics: Formulate s-domain equivalent circuit representations with initial condition sources, solve for circuit responses via partial fraction expansions, and evaluate two-port network parameters.

Required Course Materials & Approximate Costs

1. Alexander, Charles K., and Matthew N. O. Sadiku. Fundamentals of Electric Circuits. 7th ed., McGraw-Hill, 2021. Approx. $75 digital rental ($185 purchase; reserve copies available in Alkimi Library).
2. LTspice and MATLAB/Python student software (available for student download and campus workstations). Free open/educational licenses.
3. Total estimated cost: Approx. $0 (library reserve & campus tools) to $75 (digital rental).

Generative AI Policy (AI Level 2: AI Permitted with Disclosure for Specified Tasks)

In accordance with Alkimi University Academic Policies (Student Handbook §5.8), EE 202 operates under AI Level 2.

• What is permitted: Students may use AI tools to generate scripts for complex number matrix manipulation, plot frequency responses and Bode diagrams in MATLAB or Python, and clarify mathematical properties of Laplace transform pairs.
• What is prohibited: AI models must not be used to solve assigned circuit analysis problems, generate completed phasor diagrams, or perform mesh/nodal network derivations on graded homework. The use of any AI or computational assistants during examinations and quizzes is strictly forbidden.
• Disclosure: Whenever automated software or generative AI assists in writing code for circuit simulation projects, students must include an acknowledgement outlining the prompt, the code generated, and the verification methods used against SPICE simulations.

Course Schedule (Fall 2026)

Course Policies

Attendance Policy

Consistent attendance at every lecture is expected. Circuit analysis techniques, especially phasor transformations and s-domain models, require continuous guided practice. If an unavoidable absence arises due to illness or approved university events, notify Dr. Pierce in advance of class. Students who miss the first two class meetings without notifying the instructor may be dropped. Students may miss class for religious observance without penalty if they notify the instructor in writing within the first two weeks of the semester (by Wednesday, September 9, 2026). Absences for university-sponsored activities (athletics, performances, conferences) are excused with a letter from the sponsoring office at least one week in advance.

Late Work Policy

Homework problem sets submitted after the deadline incur a 15% penalty per 24 hours, accepted up to 48 hours late. After 48 hours, solutions are released and no submissions will be accepted. To accommodate unforeseen personal circumstances, the lowest homework score and lowest quiz score are dropped.

Final Exam Policy

The final examination (Monday, December 14, 2026, 1:00–3:00 p.m.) is scheduled by the University Registrar and can't be moved without the Dean's written approval (Faculty Handbook §5.5). A student with three or more final exams on the same calendar day may reschedule one of them. Requests go to the instructor of the middle exam by the last day of classes. For this term, send the request by Wednesday, December 9, 2026 (Student Handbook §6.4).
