It is a well known fact that, we cannot exist in this modern world without the knowledge of Electronics. Electronics engineering can be defined as the branch of engineering which deals with the flow of electrons (i.e., current) through the vacuum, gases and semiconducting materials. It may also be defined as the branch of engineering which deals with electronic devices and circuits.
Remember, Electrical engineering is the science which deals with the flow of electrons through the conductors (metals) only whereas, the Electronics Engineering deals with the flow of electrons through semiconductors and insulators.
We will study the applications of electronics in different fields:
1. We have electronic rectifiers which can convert AC into DC and have also ‘inverters’ which can do the reverse. Now the control in industry is through electronic and computerized operations. We are controlling our machines in our workshops through computers using computerized numerically controlled (CNC) machines.
2. It may be a wire communication like telephone and telegraph. Or, a wireless communication which is used in radio and TV broadcasting. We have photo phones in which we can see the person making the call. We have Fax system through which we can send written messages from one place to another. We have satellite communication, through which we can see TV programmes, telecast from any part of the world...
