EL 150 - Electricity II

Credit Hours: 4

Alternating current and voltage; sine wave form and values; complex numbers; polar/rectangular conversion; phase relationship; vector representation; AC series; parallel and series/parallel; R, C and L circuits; phasors; Kirchhoff’s Law; network theorems; maximum power transfer applied to AC; Resonance; Polyphase systems; delta-wye connections; three-phase voltage; current and power; vector representation; balanced and unbalanced loads and transformers.

Course Outcomes
At the completion of the course, the student should be able to:

describe the difference between DC and AC as they apply to electrical circuits with passive components;
apply AC phasor and vector theory to combinational series-parallel RLC circuit and determine the voltages, currents, impedance, phase angle, apparent power, true power, reactive power, and power factor improvement;
calculate the circuital values for series, parallel and series/parallel resonant circuits;
correctly apply electrical subscripting, symbols and units to polyphase systems;
explain basic transformer operation, list the general uses of a transformer, and apply AC theory to determine the primary and secondary values of voltage, current, power, and impedance; and
employ a systematic and methodical approach to mathematically solving circuital problems.
