JOHN A. LOGAN COLLEGE L. Barros – SP 08

ELT 100 DC/AC FUNDAMENTALS 8 cr. (4-8)

COURSE DESCRIPTION

:

DC/AC fundamentals will be approached by analyzing the basic series, parallel, and

series-parallel circuits. The analysis of AC will be continued with RC, RL, RCL, filters,

integrators, and differentiators. Circuit analysis theorems such as Thevenin’s and

Norton’s superposition will be reinforced by appropriate lab experiments.

PREREQUISITES

: None

COURSE OBJECTIVES

:

Upon completion of this course the student will be able to:

1. Given the symbol or component, identify various electronic components.

2. Given a circuit or other electronic problem, solve the problem using a calculator

and engineering notation.

3. Given an electronic circuit, use a VOM or oscilloscope to measure voltage,

current, or resistance.

4. Given a circuit problem, use Ohm=s law and the power equations to determine

current, voltage, resistance or power in a circuit or component.

5. Given a circuit problem, use Kirchhoff=s voltage law, Kirchhoff=s current law,

superposition theorem, Thevenin=s theorem, or Norton=s theorem to determine

the electrical characteristics of the circuit.

6. Given a sine wave, determine the period and frequency of the wave.

7. Given a circuit with an AC source, determine peak, peak-to-peak, and RMS

quantities as they relate to the circuit.

8. Given an RL, RC, RLC circuit, determine voltage, current, power, impedance,

and reactance in polar and rectangular form.

9. Given a range of frequencies, design, analyze, and construct high-pass, low-

pass, band-pass, and band-stop filters.

COURSE REQUIREMENTS

:

1. Tests

will comprise 80% of the final grade. Labs will comprise 20% of the final

grade. All tests except the final will count 100 points and be comprehensive.

The final exam will be comprehensive and worth 200 points. There will be no

make-up of missed tests without prior arrangements. All tests will be announced

in advance. The student’s lowest test score will be dropped. It should be

understood that attendance is mandatory. All homework and quizzes will be

added to the total points. Quizzes may be announced or unannounced. All

assigned labs must be completed and included in a portfolio in order to receive a

passing grade. Failure to turn in a portfolio at the prescribed time will result in a

failing grade.

2. Attendance

. The attendance policies as outlined in the Student Rights and

Responsibilities Handbook will be followed. Missing any or all of a lecture or lab

will be considered an absence unless prior arrangements have been made.

There will be no test make-ups unless I am notified of the absence prior to the

scheduled test. Under no circumstances will there be make-ups or quizzes.

More than 6 absences will be considered and excessive number of absences and

will result in a failing grade for the class.

3. Tools and Materials

. See attached list.

4. Zero Tolerance Policies

. See attached list.

Student Success Center

. Tutors may be obtained through the Student Success Center.

Contact the staff in C219 if this service is desired. John A. Logan College will make

reasonable accommodations for students with documented disabilities under Section

504 of the Rehabilitation Act of 1973, and the Americans with Disabilities Act of 1990.

Any student with a disability that may have some impact on work in this class, who feels

she/he needs an accommodation, should make an appointment with the Coordinator of

Services for Students with Disabilities on campus, Jennifer Frost, Room C219B, Ext.

8516. Before services can be provided, this advisor must determine eligibility and

arrange appropriate academic adjustments. It is the student=s responsibility to

register in advance of a school term with this office and to turn in a schedule

each term

to ensure that there is every opportunity for success in this class.

English Writing Center/Tutoring

. For assistance with writing assignments in any college

course, students are encouraged to visit “The Write Place” in Room E109. English

instructors are available for one-on-one tutoring each semester during hours posted at

the center.

Financial Aid

. Students who receive financial assistance and completely withdraw from

classes prior to 60% of the semester being completed (approximately 2-3 weeks after

midterm) could be responsible to return a portion of their Federal Pell Grant award.

Prior to withdrawing from courses, students should contact the Financial Aid Office.

Course Withdrawal Information

. It is expected that you will attend this class regularly.

If you stop attending for any reason, you should contact your advisor and withdraw

officially to avoid the posting of a failing grade (an E) to your transcript. It is also

advisable to discuss the situation with your instructor before dropping.
