Introduction

The tutorials that I'm preparing are a result of my life long interest in Electronics. They are intended to help other enthusiasts in their quest for better understanding the principals behind this amazing subject. I will not bog you down with history or complicated math (calculus). However, For those few that crave the mind numbing details. I will be developing sections with advanced content. On the other hand, If you are a seasoned veteran, you'll probably want to skip these basic tutorials, and move on to topics that are more your speed, or interest.

Voltage Source

As a newbe to electronics, a voltage source may seem a bit abstract. I mean, what on earth is voltage anyway's? (As technogeeks would have it : Voltage is electric potential energy per unit charge , measured in joules per coulomb). Fortunately, at this point you really don't need to know Mr. Voltage that intimately. The key for now is to understanding how voltage works.

Have you ever watered the lawn with a hose, or sprayed someone with a super soaker (water spray gun)? If not, try it some day, it's fun! Anyway's, what I'm trying to get you to understand is that, there has to be a force that causes the water to come out of the hose, or jet out of your water gun.

In the water example above, the force is called water pressure, and pressure is the key word. When dealing with electricity, Voltage is the electric pressure.

OK, now you might be wondering what electric means. Well, put simply; electric can be anything that uses or creates electricity. However, There is a bit more to it than that.
