Electronics  is the branch of science that deals with the study of flow and control of electrons (electricity) and the study of their behavior and effects in vacuums, gases, and semiconductors, and with devices using such electrons. 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 things
and repair things..
have better job opportunities

An 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.



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 atom
recognize a series resistor circuit
calculate the expected current in a series circuit
calculate the power dissipated in a resistor from color code
measure the voltage across a resistor or circuit
measure the current through a resistor circuit
recognize several types of switches
determine circuit paths in switched circuits
