Course Description
This course is a continuation of EE105. The student is introduced to the concepts and laws which describe the behavior of AC circuits. After an introduction to capacitive and inductive circuits, the behavior of RL, RC, and RLC circuits is analyzed using circuit theories. Transformer theory is also covered. A circuit simulation tool is used to build and test AC circuits and to demonstrate the use of an oscilloscope.
Course Objectives
⦁ Identify a sinusoidal waveform and its characteristics.
⦁ Apply the basic circuit rules to resistive AC circuits.
⦁ Calculate peak, peak to peak, and RMS voltage in an AC circuit.
⦁ Explain the operation of an oscilloscope as it is used to measure AC waveforms.
⦁ Explain how capacitors and inductors work in an AC circuit.
⦁ Describe how a transformer is constructed and how it increases or decreases voltage.
⦁ Describe the relationship between current and voltage in an RC circuit.
⦁ Describe the relationship between current and voltage in an RL circuit.

Attendance Policy
The University Substantive Interaction participation requirements in Week 1 overrule any course or instructor late policies for that week.
(See University Catalog for Participation and Substantive Interaction Policy)
Grantham University is committed to ensuring that each student achieves the learning objectives outlined in each course. To that end, students are encouraged to log into their course(s) to routinely interact with their instructor and fellow students, regularly participate in group discussions, and complete and submit assignments in a timely fashion.
Attendance in the First Week
Students are required to log into each of their courses to establish attendance during the first week of the course(Wednesday 12:01 am Tuesday 11:59 pm CST). A student who fails to log into any course within the first seven (7) days of the term will be automatically dropped from the course(s).
Attendance during the Term
During the term, formal attendance is not taken, but will be tracked on a weekly basis. Each student is expected to abide by attendance and participation requirements according to the criteria outlined in the course syllabus. The instructor will determine if a student s participation is sufficient to meet course requirements. A student may be administratively withdrawn (W) from the course if an instructor determines that a student s participation is not sufficient to progress in the course. A student who is withdrawn will be subject to the Institutional Refund Policy.
This course operates on a course week of Wednesday through Tuesday for 8 weeks. Days of the course week are as follows:
Day 1 Wednesday
