#### Course Description

Covers Ohm's Law, Kirchhoff's Voltage and Current Law, Superposition, Thevenin's Theorem, and R-C circuits. Includes labs on basic measurement techniques, use of electronic test equipment and proper documentation procedures. Prerequisites: WR 115, and placement into MTH 95. Audit available.#### Addendum to Course Description

The laboratory portion of this course provides students with the opportunity to develop skills in the operation of basic electronics test instruments (dc power supply, digital multimeter, signal generator, and oscilloscope). Students will work in groups of two or more to perform and complete laboratory exercises. Students must be able to communicate, both in oral and written form, using the English language.

The course may be offered on line also, in a DL format. In that case, the labs will be held in the lab room of the school, once a week, for 3 hours.

#### Intended Outcomes for the course

Upon completion of the course students should be able to:

- Construct, analyze and troubleshoot DC circuits.
- Operate electronic test equipment: multimeter, power supply, function generator, oscilloscope.
- Use electronic circuit simulation software like PSpice
- Communicate technical information in written and oral form
- Practice safe operating procedures.

#### Course Activities and Design

The course will include a variety of learning activities. The lecture portion of the course, three hours per week, will include instructor delivered lectures and demonstrations stressing key topics in the course. In preparation for the lecture portion of the course, students will be expected to complete all reading and homework assignments.

The laboratory portion of the course, three hours per week, will include laboratory activities. The purpose of the laboratory activities is to develop skills in the operation of basic electronics test instruments, skills in circuit analysis and troubleshooting, skills in teamwork, and skills in oral and written communication.

#### Outcome Assessment Strategies

Assessment of student performance in this course will be conducted in both the lecture and the laboratory portion of the course and will be in the form of written and practice-based questions.
