This control of electrons is accomplished by  devices that resist, carry, select, steer, switch, store, manipulate,  and exploit the electron.Electronics isn't always easy, but you can learn. And you can do it  without memorizing theories and formulas belong in a Physics text. the  focus of this program is learning how things work. Electronics may  defined as an art of knowledge to make such impossible things work.  Things such as Televisions, AM/FM Radios, Computers and ob course the  mobile phones and etc. We are  surrounded by electronics....Learning how things work can be fun. With this skill you can Build things.make better use of thingsand repair things..have better job opportunitiesAn important part of learning electronics is the the need to visualize the action inside a piece of equipment. In  electronics things happen at a sub-atomic level. to understand what is  happening, you need a mental picture, a visualization  of events you can  see directly. You need a in your mind of how events are turned on and  off. you need to visualize signals being amplified and attenuated. (  These are long words for being made bigger and smaller )take an overview of electronic equipment. Inside anything what's  happening can be describe as some kind of source delivering power to  some kind of a load. The terms source and load become clearer as you can  discover a few basics. A source is where the energy comes from. A load  is what does the work. When power is delivered to a load, the load  produces sound, heat, pictures or anything else that can be produced  electronically..<img src="http://lh3.ggpht.com/_8JZhVVmpICU/S74lO3l1ytI/AAAAAAAAAIE/haIqNfuspPc/source%20and%20load.gif" alt="" class="fr-fic fr-dii fr-draggable " style="" />Dow load this Tutorial Software below, In this program you will learn  some useful hints about basic electronics, the program includes some  exercises to have fun with....On successful completion of this lesson you will be able to:describe  the structure of a simple atomrecognize a series resistor  circuitcalculate the expected current in a series circuitcalculate  the power dissipated in a resistor from color codemeasure the  voltage across a resistor or circuit measure the current through a  resistor circuitrecognize several types of switchesdetermine  circuit paths in switched circuits</blockquote>
