TEL 102 - A C Analysis

This course extends the basic concepts introduced in DC Analysis (TEL 101) to incorporate time-varying voltages and currents. AC (Alternating Current) circuit analysis introduces the basic behavior of capacitors and inductors, as well as series/parallel circuits. Students also learn to analyze Power (real, reactive, apparent) in various AC circuit configurations, including series/parallel resonance. Upon successful completion of this course, students should be able to: Convert circuit elements from time domain to phasor (complex) representation and from phasor back to time domain; Analyze currents and voltages in Rl, Rc, Rlc circuits using phasors; Use software simulators to obtain various currents and voltages in Rl, Rc, Rlc circuits; Calculate reactive, apparent, and real power in single phase and multiphase circuits; Analyze series and parallel resonant circuits; Analyze transformer circuits; Demonstrate knowledge of safety in the use of various test equipment; Produce an accurate and neat laboratory report.
