Definition of Electronics:
Electronics is that 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 that belong in a Physics text. The focus of this program is learning how things work. Electronics may be defined as an art of knowledge to make various otherwise impossible things work by manipulating the flow of electrons. Things such as Televisions, AM/FM Radios, Computers and mobile phones. Today, we are surrounded by electronics in almost every sphere of life.
Learning how things work can be fun. With this skill you can Build things; make better use of things; and repair things - even 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 to visualize those events. You need a clear picture in your mind to undesrtand how these events are turned on and off. You need to be able to visualize signals being amplified and reduced
Inside any gadget or device whatever is happening can be described as some kind of source delivering power to some kind of a load. The terms source and load become clearer gradually. A source is where the energy comes from. A load is the work that is done. When power is delivered to a load, the load produces sound, heat, pictures or anything else that can be produced electronically. This produced sound, heat, pictures, etc. are the work done - load.
Now that we are clear about Source & Load, we need to clear a few more concepts to better understand the basics of electronics. Please click on the link below to get in-depth knowledge on each of the topics. Do remember that on clicking this link, a new tab/window will be opened, and you will be taken to an external site (www. electronicshub.org). Once you've finished reading just close that tab/window and you will automatically be back here, where you left off. It is recommended that you study this set thoroughly before proceeding further with our tutorial.
