EDT 207 - AC Power
Credits: 4
4 Skills Lab Hours
Description
This course is a study of basic atomic theory and electrical theory. Students learn how to apply Ohm’s law to series, parallel, and series-parallel circuits and how the power equation can be used to determine unknown values in a circuit. Students also learn electrical schematic diagrams, alternating current (AC) and direct current (DC) electrical principles and single-phase and three-phase AC power characteristics. Topics include single-phase and three-phase transformer operations, phase-to-phase and phase-to-neutral voltage, current and power factors.
Learning Outcomes
Upon successful completion of the course, the student will:
- Define basic terms of electricity.
- Apply Ohm’s law to series circuits and parallel circuits.
