Course Outline
Electricity is all around us – powering technology like our cars, computers and mobile phones. Electrical power and electronics industry are now the backbone of our modern society. This course introduces the history of electrical and electronic technology development, the fundamental concepts of DC/AC electricity, and the characteristics of semiconductor devices and circuits. Emphasis is placed on DC/AC circuits, components, and other related topics. Upon completion, students should be able to appreciate the vital role played by electricity in our life, and be able to identify, construct, verify, and analyze simple DC/AC circuits. The course contents are based primarily on a film entitled "Understanding Electricity" by the Discovery Channel and a Federal Aviation Administration publication "Basic Electricity" (Chapter 10 in FAA-8083-30). This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
At the conclusion of this course, the student will be able to:
- Understand the history of electrical and electronic technology development;
- Identify electrical symbols and measuring instruments;
- Use Ohm’s law to find unknown values and calculate voltage drop;
- Define a series circuit and their properties;
- Define a parallel circuit and their properties;
- Solve a combination circuit using the laws of series and parallel;
- Explain how capacitance and inductance influence voltage and current relationships;
- Use an electrical meter to measure voltage, amperage, and ohms; and
- Appreciate the vital role played by electricity and electronics in our life.

Course Summary
The discovery of electricity is one of the greatest achievements of man. The three primary forces in electricity are voltage, current flow and impedance (resistance). They are the fundamental forces that control every electrical circuit. This course covers the concepts of electrical theory necessary to design, install, maintain, and troubleshoot electrical circuits.
