Catalog Course Description

Covers the fundamentals of DC and AC circuits and circuit calculations. Examines electrical definitions, units of electrical measure, use of meters, series and parallel resistive circuits, capacitance, and inductance. Also explores basic wiring techniques and how to troubleshoot circuit faults.

Goals, Topics, and Objectives

Goal Statement

To educate and familiarize students with electrical basics related to troubleshooting because 70% of equipment problems are related to electrical failures.

Core Course Topics
  1. DC and AC Electricity
  2. Electrical Safety
  3. Series/Parallel Circuits
  4. Ohm's Law/Power Formula
  5. Electrical Components
  6. Electrical Wiring
  7. Troubleshooting
Core Course Learning Objectives (Separated)
  1. Describe concepts of basic electricity theory; and define terms voltage, current, resistance, and power.
  2. Demonstrate in labs and on exams basic electrical safety.
  3. Demonstrate Ohm's law and power calculations in an electrical circuit.
  4. Describe concepts of series and parallel circuits, and explain the differences between them.
  5. Describe concepts of capacitance and inductance.
  6. Describe concepts of AC theory, and be able to differentiate it from DC.
  7. Demonstrate a working knowledge of how and why conductor size and type affect the flow of current; be able to calculate proper conductor size in a circuit.
  8. Demostrate transformers, resistors, and relays/contactors usage.
  9. Explain single-phase current and three-phase current.
  10. Calculate line loss in an electrical conductor, good conductors vs. poor conductors, and semi-conductors.
