Course Description
 This
course covers quantities encountered in AC electric circuits. Analyzing
AC circuits using impedance, admittance and phasor to obtain any required
circuit quantities as current, voltage, power, and frequency. This course
examines the concepts of frequency and phase relating to a sinusoidal waveform.
This course explores the circuit variables of AC on capacitors, inductors,
RC circuits, and RLC circuits. The course introduces the concept of the
resonance in RLC AC circuits. This course will direct the student through
each new concept by utilizing a balanced approach of theory and computer
simulation lab projects. (3/30/45/0/0/5)
 General
Objectives
The student will have a fundamental understanding
of the meaning of the capacitive and inductive reactance and of their behavior
as functions of frequency. The student will be able to discuss the concept
of the lead/lag relationship between the phase angle of a waveform and
the phase shift between waveforms. The student will have the ability to
calculate voltages, currents, real power, complex power, and reactive power.
The student will have the ability to analyze AC series and parallel circuits
containing R, L, and C components. The student will also develop basic
troubleshooting techniques for a sinusoidal waveform in series and parallel
circuits.
