ELT 110 - Introduction to Electricity

Course Description

This introductory course introduces students to the fundamental theories and principles of electricity. These theories and principles include voltage, current, magnetism, Ohm’s Law, inductance, capacitance, and resistance, as well as the basics of DC circuits, their applications, and associated symbols. The course emphasizes safe working procedures in a construction environment.

Upon successful completion of this course, students should be able to:

Interpret electrical drawings, including site plans, floor plans, and detail drawings.
Measure current, resistance, and voltage in DC circuits.
Calculate volt-amperes per foot for calculating general lighting loads.
Compute electrical loads and select proper conductor sizes and over-current devices for dedicated circuits in compliance with NEC.
Select the proper code requirements for calculating branch circuit sizing and loading.
Demonstrate proper installation techniques for basic electrical wiring.
Apply safe electrical practices and the basic safety rules for working on electrical systems.
Demonstrate an understanding of the shock hazard associated with electrical work.
