# EE 2725 - Linear Circuits III: AC

3 lecture hours 0 lab hours 3 credits
Course Description
This third course (in a series of three) is a continuation of EE 2715 with the emphasis now being on AC circuit analysis and the use of frequency as a variable. Following a brief review of basic DC circuit analysis techniques, emphasis will be given to complex numbers and the use of phasor notation, impedance, complex AC power, mutual inductance, transformers, RL and RC filters, and Bode plots. AC circuit analysis in both the time and Laplace domains along with the concepts associated with transfer functions will also be included. The significance and control of 60 Hz leakage currents from medical devices, and electrical safety in hospital environments will also be emphasized. The use of MultiSim as an analysis and simulation tool is used throughout the course. (prereq: EE 2715 )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
• Possess a working knowledge of complex numbers and phasor notation in the analysis of AC circuits
• Analyze and solve for AC currents, voltages, and impedances in both the time and Laplace domains
• Recognize the sources and significance of phase shifts between AC currents and voltages in AC circuits
• Understand the definitions of, the differences between, and be able to calculate the average, reactive, and apparent power in AC circuits and be able to graphically represent their interrelationships through use of the power triangle
• Understand the design, behavior, applications, and basic calculations associated with transformers
• Understand the origin, significance, and design control of 60 Hz leakage currents in AC line powered devices in general and medical devices in particular
• Recognize, design, and analyze passive low, high, and bandpass filters in both the time and Laplace domains - including series and parallel resonance
