#### Course Description

Covers AC circuits. Includes both single frequency and frequency response analysis of circuits containing resistance, capacitance, and inductance. Both trigonometry and phasors will be covered. Labs include circuit construction, computer simulation and testing. Prerequisites: MT 111; 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 electronics test instruments (signal generators, digital multimeters and oscilloscopes). 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 also in a distance learning format. In that case, the lecture will be delivered on the web while the lab experiments will be done in the class room (three hours per week).

#### Intended Outcomes for the course

- Construct, analyze and troubleshoot AC 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.

The course will include a variety of learning activities. The lecture portion of the course 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 is intended to enhance skill in the operation of basic electronic test instruments, skills in circuit analysis and troubleshooting, skill 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/or practice-based questions.
