The Absolute Basics of Electricity
If your home inspector ever told you that one of your receptacles had reverse polarity or an open ground, there is a good chance you had no idea what he was talking about. Because it’s more difficult to visualize electricity; it can be harder to grasp the basic concepts.

Electricity can be just as simple; let’s use this crude hand-drawn diagram to break it down to its simplest terms and take a look at the common defects a receptacle can have.
