Course Description

In this course you will get an breif description of how electricty is made and how that creation reacts as it goes through its delivery to the devices we commonly see and use. Understanding the reaction of electricity and how each component reacts will give you a better ability to understand failures. When you have a failure, you will know why. Electricity uses a series of magnetic fields to get to the components we work with, those magentic fields induce the work being done on our end. In each Component section we will describe how the component works in its simplest form. The course is designed to avoid heavy confusing equations typically used in electrical design but still touching on some easy to use equations commonly used. This course covers how electric flows, what it flows through and what it does not flow through. It covers how to use typical meters. It covers some basic readings to use with your meter. It covers testing of each component we describe, again in the simplest way possible.  This course also covers some applications components may be used in and some common failures. This course also covers common connectors, insulation and wire types.

Many students with some experience describe it as a great refresher course reminding them to remember the basics.

Clear and practically focused. Information intended for knowledge that leads to use.

By Kevin Blatter on 8/27/2026

As a homeowner that has had to troubleshoot his own circuits using a Multimeter, I realize that I knew more than I thought I knew, but this course has confirmed what I knew and added a few tidbits along the way that I never fully understood.

By Le'Ondra Hinton on 7/6/2026

It’s a lot to take in, but overall it is a great course and gives me a great understanding of atoms, electrons and current flow

By Joseph Bishop on 1/26/2026

It's so nice to find a course on here from someone I can actually understand! Good information explained clearly. The video production isn't the best and has a lot of audio dubbing, but still a worthwhile course.

By Richard G Shanks on 1/13/2026
