ENGR& 204 Electrical Circuits (6 credits)
Distribution Area Fulfilled General Transfer Elective
Prerequisite PHYS& 223 and MATH& 163 with at least a 1.5 grade in each of these courses
Course Description
An introduction to electrical engineering through basic circuit and system concepts. Topics include: resistors, sources, capacitors, inductors, operational amplifiers, node and mesh analysis, Thevenin and Norton equivalents and RLC circuits. Solution of first and second order linear differential equations associated with basic circuit forms will be used.

B. The “alphabet” of circuit schematics (resistors, wires, sources, etc)
C. Analysis, graph theory concepts: loops, nodes, supernodes
D. Kirchhoff’s current and voltage laws
E. Ohm’s law
F. Series and parallel resistor combinations, voltage and current division
G. Thevenin and Norton equivalents; linearity and superposition solution methods
H. Source transformation
I. Linear algebraic techniques (node analysis; loop/mesh analysis)
J. Capacitors and inductors
K. Introduction to AC analysis and waveforms
L. Complex numbers
M. Phase analysis
N. Impedance in the frequency domain
O. RC, RL and RLC circuits
P. Power/Impedance triangles
Q. Power factor
R. Transformer
S. Electrical safety
T. 1st and 2nd order circuits in the time domain
Student Outcomes
1. Identify linear systems and represent those systems in schematic form.
2. Explain precisely what the fundamental circuit variables mean and why the fundamental laws governing them are true.
3. Apply Kirchhoff’s current and voltage laws, Ohm’s law and the terminal relations describing inductive and capacitive energy-storage elements to circuit problems.
4. Simplify circuits using series and parallel equivalents and using Thevenin and Norton equivalents.
5. Perform node and loop analyses and set these up in standard matrix format.
6. Explain the physical underpinnings of capacitance and inductance.
7. Identify and model 1st and 2nd order electric systems involving capacitors and inductors.
8. Predict the transient behavior of 1st and 2nd order circuits.
9. Analyze AC steady-state responses in terms of impedance.
10. Analyze AC circuits in the frequency domain, including resonance.
11. Perform DC and AC steady-state power calculations.
12. Build circuits on breadboards and perform electrical measurements
