Class Attendance

Regular attendance in lecture is expected and necessary in order to do well in this course. Most of the material you are responsible for will be presented in lecture with the balance coming from reading, homework and lab assignments.  Laboratory attendance is vital to understanding the material.  If you have a justifiable need to miss lab, contact your instructor ahead of time.

 

Late Work

Any pre-lab, lab report, or homework handed in late will automatically loose 50% of the possible points.  Any pre-lab, lab report, or homework handed in more than one week late (or after the final exam is given) will receive NO points.  

 

Homework

Homework assignments will be assigned during lecture (with due dates). Always rewrite the problem statement for each problem, and draw a box around each answer asked for in the problem. Also, all work must be shown (and easily readable) in order to receive full credit for the problem.

Lab Procedures

Lab experiment procedures are contained in the EET 107 Introduction to Circuit Analysis Laboratory Manual

 

Pre-Lab

Prelab includes all "Objectives", all "Expected Values" and all supporting "Calculations" or "Sample Calculations" of "Expected Values".  Prelab work must be recorded in the EET 107 Introduction to Circuit Analysis Laboratory Workbook and the completed pages handed in at the beginning of the lecture which immediately precedes the Lab.

 

Lab Report

Lab measurement data, and lab analysis answers must be recorded in the EET 107 Introduction to Circuit Analysis Laboratory Workbook during the lab period and the completed pages must be handed in at the beginning of the lecture which immediately precedes the lab period in the following week. In addition to the correctness of you results, the neatness, grammar, and overall professionalism of your report will be evaluated.

 

Cheating Policy

Students are encouraged to work together and learn from each other.  However, cheating in any form may result in a failing grade for the course and notification made to the Dean of Students office.

 

Safety

The following policies insure the safety of everyone in the Lab:

- No food, drink, or smoking allowed in the labs.

- Shoes must be worn at all times in the lab.

- Coats, backpacks, books, etc. must NOT be stored on top of equipment due to overheating; these items should be stored beneath the lab benchtop.

- No student is allowed to work in lab without an instructor's supervision.

- Remove all personally worn conductors such as jewelry.

- Use only one hand to make measurements on live circuits and grasp probes by there insulated part.

- Turn off power when making connections or changes to your circuits.

- If you believe someone is being electrocuted, don't touch them or their equipment -- HIT THE LARGE RED BUTTON located near the door to the lab. This will cut off all power to the lab.

- Always assume soldering irons are hot and always wear goggles when using them.

- Always cut wires in a direction away from your hands and others.

- Beware of frayed wires, and report any damaged wires or equipment to lab instructor.
