About This Course:

This course will provide students with hands-on experience with elementary electrical and electronic devices and circuits including capacitors, inductors, and operational amplifier circuits; ac and dc measurements; and frequency response.  While non-linear circuit analysis is in sight, the focus of the course is on linear time invariant circuits. The analysis of the electrical circuits based on circuit theory theorems in both time and frequency domain are going to be considered.

Course outline:

1.      Introduction to Oscilloscope

2.       Introduction to digital multimeters

3.       Resistive Circuits

4.       Operational Amplifiers

5.       Time response of first-order circuits

6.       Time response of second-order circuits

7.       Nonlinear circuits

8.       Frequency response of first-order circuits

9.       Frequency response of second-order circuits

10.   Impedance matching and timer 555

11.   Three-phase Circuits

Instructions:   Before your lab section meets, read and study the Pre-lab document for the upcoming experiment. Work the pre-lab exercises. Some of the pre-lab exercises require simulation. When you come to lab, bring your completed pre-lab exercises, and hardcopy of both the present experiment pre-lab and  previous experiments in-lab documents. You can print out the pre-lab and in-lab procedure for each experiment and bring it to lab or email lab reports to course email address.

Format of Experiments

Each experiment is organized into five sections:

• Introduction. A short summary of the topics and objectives for the experiment

• Theory. Major principles, equations, etc. relevant to the experiment.

• Prelab Assignment. Assigned reading and homework to be completed before coming to lab.

• In-Lab Procedure. A detailed specification of the experimental work to be completed during the lab meeting time.

• Review and Report. During each experiment, you will collect data, perform calculations, and make observations. These should be recorded and included in a report to be submitted to the lab instructor before leaving the lab. The report will also contain answers to any specific questions posed in the lab manual.

Laboratory Report Format

You must turn in your lab report before leaving lab at the end of each experiment. Your lab report will be graded by considering technical content, organization, presentation, grammar, spelling, care in drawing, and use of professional terminology. The required format is as follows:

1. TITLE PAGE:

TO: Instructor's Name

2. INTRODUCTION: A short summary of the experimental objectives in the student's own words, and any information you think the instructor should consider while grading the report, such as equipment problems.

3. IN-LAB PROCEDURE: Include observations, data, and calculations obtained during the experiment.

4. CONCLUSIONS: A summary of what was learned in the lab. Comments about how to improve the experiment are welcome.

Homeworks

Resources

you can download laboratory manual from here. The laboratory manual will be published in PDF format, and you will need to use Acrobat Reader to access it.

For simulation of lab circuits you require Orcad Pspice software. A good tutorial for Pspice exist here.

Also exist a useful applet for analog circuits that you can download it from here. An applet is any small application that performs one specific task; sometimes running within the context of a larger program, perhaps as a plugin. For more information about applets please refer to the Wikipedia. You should be able to view the applet with any Java-capable browser. If you don't have Java, get the Java plug-in.

Resistor Color Coder is a free useful desktop application for determining the color codes or values of 4 and 5 band resistors. You can download it from here.

Text Book: Electric Circuits, James W. Nilsson and Susan A. Riede, eighth Edition, 2008.

Laboratory Rules:

• You are expected to remain in the laboratory for the full class period. If you finish early, you should use the remaining time to start the pre-lab work for the next week's experiment. 
• If you are unable to attend a lab meeting, you should arrange a make-up with your instructor. At your instructor’s discretion, you may be assigned to visit another section the same week if your schedule permits, or your makeup may be scheduled during the last week of classes.
