of electrostatics, magnetostatics, time-varying electric and magnetic phenomena, direct and alternating current circuits, elementary electronics and electromagnetic waves. Emphasis is placed on
the mathematical analysis of physical problems. Laboratory work on various aspects of electric
and magnetic phenomena emphasizing direct current (DC) and alternating current (AC) circuits is

12. Analyze the results of problems solved and assess the real-world applications.
Adding/Dropping: It is the student’s responsibility to add, drop, or withdraw from classes before
the deadlines stated in the class schedule. Petitions to add, drop, or withdraw after the deadline
will not be approved without proof of circumstances beyond the student’s control which made
him/her unable to meet the deadline. Lack of money to pay fees is not considered an extenuating
circumstance. Students anticipating difficulty in paying fees before the add deadline should check
with the Financial Aid Office about sources of funds or other alternatives for which they may be
If you decide to withdraw from this course, you are reminded to do so before the 6th the week
of instruction (with a “W”). If you fail to withdraw by that date and you stop coming to class, a
final grade must be assigned to you.
Policy: Attendance is taken every class, in both lecture and lab sections. Any student who fail
to attend the first day of class will be dropped from the class. A maximum of 3 absences are
allowed for the class and any student who exceed this amount will be dropped. Note
that being absent for lab and lecture counts as 2 absences. This is in compliance with the
Mesa College policy on attendance.
If students miss class, please make arrangements with a classmate to keep you informed on
lecture topics, lab or studio exercises, handouts and assignments. This information is an integral
part of the instruction and may not be found in the reference texts.
The class begins at the listed time on the catalog. A ten-minute break will be taken approximately
for each hour of class. Since the classroom is considered a professional setting, tardiness is unacceptable. In addition, it is also disruptive to both the instructor and the students. Students who arrive
more than 10 minutes late to class or who leave in between the break-period will be considered
absent for the day.
Classroom Behavior and Student Code of Conduct: Students are expected to respect
standards of student conduct while in class and on the campus. Refer to Policy 3100, Procedures
3100.1 and 3100.2, current college catalog and student handbook for guidance.
In particular, any form of cheating and plagiarism will not be tolerated and can result to an “F”
letter grade for the assignment, project, or exam for all those who are involved. Also, all violations
of standard academic honesty will be reported to the school dean for appropriate action.
Accommodations for Disability: Students with disabilities who may need academic accommodations should discuss options with the professor during the first two weeks of class.
Lab Sections:
I will start each lab section by just briefly describing the equipment, which includes concerns or tips
in regards to its use. Therefore, all students are expected to have read the necessary background
information and instructions prior to starting the lab assignment. In addition, students who
arrive more than ten minutes late to the lab section without prior notice will not be
allowed to participate and will receive a zero for the experiment. Disruptive or dangerous
behavior is not tolerated and will result in the removal of the student from the session and the
course. No food and drink are allowed in the labs. Closed-toed shoes are required and any
student who do not comply will not be allowed to participate for that day’s lab activity.
Evaluation: The following lists the weights for the different course components and their
• Exam (45%): There are four exams for this course, with the dates listed on the schedule.
Exams will cover recent course material throughout the semester. The lowest exam score will
be dropped and the three best will count toward the final grade. All exams are closed-book
but students can produce a “cheat sheet” on one side of an 8.5′′ × 11′′ sheet of paper. No
make-up exams are given, under any circumstance.
• Final Exam: (15%) The final exam is cumulative, which will include multiple-choice conceptual and calculation-based questions. Students can use a “cheat sheet” on both sides of an
8.5′′ × 11′′ sheet of paper. Exemption from the final exam is possible if and only if a
student obtains a curved score of 90% or higher in the previous four exams.
• Lab Reports (15%): Students will perform laboratory experiments with groups of 3-4 students,
depending on the number of setups available. Each group is responsible for picking their own
groups and one lab report is required for submission for each group. The pdf files for
each experiment will be available on Blackboard.
Completed lab reports are due the next lab (or an exam) session, within ten
minutes after starting. No late work is ever accepted and no make-up sessions
are offered under any circumstance. The lowest lab report will be dropped from your
final grade.
The grading rubric for the lab reports are roughly as follows:
50% for Thoroughness
– All prompts answered completely
– All calculations clearly displayed
– All plots properly prepared
30% for Experimental Accuracy (may vary depending on the lab)
– < 5% error is excellent
– 6 − 10% error is acceptable
– 11 − 15% error is tolerable
– 16 − 20%is substandard
– > 20% is unacceptably large
20% for Legibility
– Proper grammar is used
– Proper spelling is used
– Work is clear and easy to read
• Take-Home Quizzes (20%): Take-home quizzes (THQ’s) are given about every week and composed of both conceptual and calculation-based questions. They are typically due one-week
after they are assigned. These are to be submitted in-class within ten minutes after
lecture starts or in my mailbox if to be submitted earlier than the due-date. Absolutely
NO late work is accepted, under any circumstance. All take-home quizzes MUST
have the following format:
– Last name, first name on the upper right-hand corner.
– At the beginning of each calculation-based problem, paraphrase the question.
– Present answers only on one side of the paper. The tutoring center has paper with one
blank side available.
– Write answers in scientific notation in cases of leading zero’s or when answers have five
or more digits.
– Write answers with the appropriate number of significant figures.
– Write legibly. Illegible work cannot not be graded.
– For answers involving multiple-line calculations, each step must reflect and a coherent
train of thought to the reader.
– Box all final answers and must include the proper units.
– Assemble the solutions in sequential order and staple them together on the upper left
For each THQ, one conceptual and calculation-based problem will be graded, chosen at
random. The solutions for all the problems in the THQ will be posted within 1-3 days after
• In-Class Quizzes (5%): In-Class Quizzes (ICQ’s) are 15-20 minute one or two question announced quizzes that are taken during class. They are designed to assess understanding of
current material, identify areas of weakness, and simulate an exam-like environment.
Grading Scale:
90 − 100% = A, 80 − 89% = B, 70 − 79% = C, 60 − 69% = D, > 60% = F
Important Dates:
Last Day to Drop with a Refund, without a “W”: June 15, 2015
Last day to Withdraw: July 10, 2015
Contacting Me:
I check email regularly throughout the workweek until 9 PM. Therefore, please plan accordingly
when sending me an email. My office hours are listed above and these are the times that I will
be available on campus outside of the classroom. Please be respectful of this time slot and do not
expect to be accomodated outside of this time.
