Mesh and nodal analysis techniques are introduced to
handle dc network problems. Network
analysis theorems, such as source transformation, Thevenin's
theorems, Norton's theorems, superposition, deltawye
resistor transformations and the maximum power transfer theorem are used to
simplify circuit analysis. These
topics are extended to simple ac circuits through the introduction of phasor analysis and the impedance concept. Series and parallel ac circuits are
analyzed using phasor methods. The frequency response of simple RC, RL
and RLC circuits are covered. The
frequency response of resonant circuits is covered. The frequency response of circuits is
plotted using bode plots. Bode
plots are used to describe the response of simple RC and RL filter circuits
with and without attenuation.
At the end
of this course, you will be able to:
1.) Recognize
ideal dc current sources and list how they can be applied in practical
application.
2.) Perform source conversions between dc voltage
and current sources.
3.) Analyze a dc
network containing multiple sources using mesh and nodal analysis.
4.) Analyze a dc
bridge network and apply it to measure resistance.
5.) Use the
deltawye component conversion formulas to simplify
dc networks.
6.) Use the
Superposition Theorem to find the response of circuits with multiple sources.
7.) Use Thevenin's and Norton's Theorems to simplify dc circuits.
8.) Find the
maximum power transfer between a dc load and a source.
9.) Use the concept of impedance to represent
components in an ac circuit.
10.) Plot the impedance of R, L and C to
varying frequency sinusoidal inputs.
11.) Find the average power dissipated
and power factor of an ac load.
12.) Perform
complex number arithmetic.
13.) Use
complex numbers and vectors to develop the phasor
representation of ac.
14.) Construct
Impedance diagrams and phasor diagrams for simple ac
circuits.
15.) Find
the impedance, voltage, current and power for series and parallel ac circuits.
16.) Determine how changing ac frequency
affects voltage and current in ac circuits.
17.) Analyze
and design circuits that exhibit series resonance.
18.) Construct
Bode plots to determine how simple ac circuits respond to changes in source
frequency.
19.) Analyze
and design simple filters using RC combinations.

1.) Kirchhoff's Voltage and Current Laws
The propose of this laboratory activity is to become
familiar with Kirchhoff's voltage and current laws. Students will also familiarize
themselves with dc circuit measurement techniques and lab instrumentation. These skills will be used to do simple
circuit analysis.
2.) Mesh Analysis and Solution of Simultaneous
Equations Using Spreadsheets
Mesh

3.) Nodal Analysis and Measurement Error Estimation
The
purpose of this lab activity is to become familiar with nodal analysis. The propagation of error and measurement

SIUC is committed to providing a safe and healthy environment for study and work. Because some health and safety circumstances are beyond our control, we ask that you become familiar with the SIUC Emergency Response Plan and Building Emergency Response Team (BERT) program. Emergency response information is available on the BERT website at www.bert.siu.edu, Department of Public Safety’s website www.dps.siu.edu (disaster drop down) and in the Emergency Response Guidelines pamphlet. Know how to respond to each type of emergency.
Instructors will provide guidance and direction to students in the classroom in the event of an emergency affecting your location. It is important that you follow these instructions and stay with your instructor during an evacuation or sheltering emergency. The Building Emergency Response Team will assist your instructor in evacuating the building or sheltering within the facility.
