HAVE SOME INFMN ABOUT ELECTRONICS

We are living in an age of Information Technology. Electronics is at the very foundation of the Information and Computer Age. The giant strides that we have made in the areas of Communications and Computers are possible only because of the great successes that we have achieved in the field of Electronics.

It is sometimes unbelievable, how many electronics gadgets that we carry these days in our person –Digital Wrist-watch, Calculator, Cell-phone, Digital Diary or a PDA, Digital Camera or a Video camera, etc.

The different types of Electronic equipments that has invaded our offices and homes these days is also mind boggling. Many things we use at home and office are “remote controlled”, for example, Television (TV), Air-Conditioners, Audio equipment, Telephone, etc. It is almost close to “magic”how even a child, now-a-days, can switch channels, or increase decrease the volume of sound in a TV at home by just clicking on a few buttons sitting at the comfort ofa sofa away from the Television apparently without any physical wiring or connection!

Again, we are astonished, how we are able to talk to ournear and dear living several thousands of kilometers away, from wherever we are, at home, office, on the road in a car, or in a classroom –by just clicking a few n umbers on our palm sized cellular phones

Electronics has made deep impact in several vital areas such as health care, medical diagnosis and treatment, Air and space travels, Automobiles, etc. In short, the technological developments of several countries of the globe are directly related to their strengths in electronics design, manufacture, products and services.

It appears as though we have to add inevitably an “E” to the three “R”s, namely, Reading,wRiting, and aRithmatic, to declare a Man or Woman to be “literate”! Needless to add that the “E” here means “Electronics”! Thus Electronics has become surely a “BasicScience”. It is no more an “applied science”. Just as we teach physics, chemistry, biology and mathematics in our schools, it is high time we start teaching our children at school, Electronics as a separate subject by itself

.This brings us face to face to an important question : How to teach the basic concepts of such an important subject like Electronics most effectively? If one wants to gain a good understanding of electronics, he or she should build circuits and test them independently. For this one should acquire a practical knowledge of the characteristics of different devices and in constructing the various circuits. Let us try to learn such skills by the proven scheme of “ LEARNING BY DOING”.

An old Chinese Proverb says:
•I Read -I Forget
•I See -I Remember
•I Do -I Understand
There is only one way to learn to do anything: JUST DO IT!
