The Two Most Useful Equations in Electronics

Saturday, June 25th, 2011

There are two important equations that are used in every electrical project. A person can usually debug an electrical circuit using only these two equations, so long as they are good with logic or algebra. However, before we can discuss them, we need to cover two more definitions.

Basic Electrical Concepts

Friday, June 24th, 2011

In previous posts, such as my solar powered pond pump pages, I’ve tried to pass on hands-on knowledge of how to build solar circuits. However, I rely on a common foundation of electrical concepts such as voltage, current, resistance, etc. I assume that my readers are familiar with these concepts, but this is not always a valid assumption. This post covers some basic electrical concepts that need to be understood by anyone wanting to work with electrical solar circuits. Each definition below includes links you can follow to get more information on that topic.
