Course Description

Analysis of electric circuits, including DC circuits, network theorems, energy sources, transient analysis, sinusoidal analysis, phasors, AC power, and frequency response of circuits. Lab will include connection of circuits and observation of circuit behavior using electronic instrumentation. PREREQUISITE: MATH A285 or MATH A285H, or concurrent enrollment; and PHYS A280. Transfer Credit: CSU; UC.

Course Level Student Learning Outcome(s)

Mathematically analyze the electrical behavior of DC, AC, and switching transients circuits.
Utilize a computer circuit analysis and simulation program to analyze DC and AC circuits.
Work with electronic test equipment to build and analyze circuits. This will include voltmeters, ammeters, DC power supplies, function generators, and oscilloscopes.

Course Objectives

1. Identify basic circuit components on a schematic drawing.
2. Analyze electric circuits for voltage, current, power and energy values.
3. Use techniques of mesh and nodal analysis.
4. Apply Thevenins and Nortons theorems to analysis of circuits.
5. Solve first and second order transient problems.
6. Find the transient response and complete response for RC, RL, and RLC circuits involving DC sources.
7. Use phasors and complex algebra in AC analysis problems.
8. Connect electric circuits in the lab.
9. Measure resistance, current, AC and DC voltage and power values. Experimentally verify these values for a variety of electrical circuits.
10. Test circuits, analyze data and compare measured performance to theory and simulation.
11. Use oscilloscopes and amplifiers.
12. Use diodes in combination with other electric components.
13. Implement rectifiers and power supplies.
14. Use a circuit simulation program (e.g. PSpice, Multisim, etc.) and other computer applications (e.g. MATLAB, MS Excel, etc.) to predict or describe circuit behavior.
15. Troubleshoot and repair simple electric circuits.
16. Record and document results of lab work using text and graphs.
17. Work effectively in groups by sharing responsibilities and collaborating on findings.
