What is Electronics?
As the name suggests, “Electronics” is directly related to the electrons, which means how an electron behaves when it is subjected to externally applied electric and magnetic fields. The word electronics is derived from electron mechanics.
So basically, electronics is a branch of engineering that deals with the flow of current through any form of matter, semiconductors, gases etc. It also deals with the theoretical study of devices and their applications in real life.
Electronics is an enormous field and is particularly classified as:
- Physical Electronics
- Electronics Engineering
To analyse the motion of electrons in mediums like gas, vacuum, or semiconductors, physical electronics are used. Whereas electronics engineering deals with the designing, fabrication, and application of electronic devices.
What is the Importance of Electronics?
As we know that electronic applications tend to play a major role in everyone’s lives, a wide range of applications of electronics has made our lives more efficient, and that’s why electronic gadgets or machinery are one of the best ways to increase our efficiency and save time.
Electronics are an essential part of our lives because it has not only helped to fulfil our individual needs but also helped with the growth of technology and the economy as a whole. Also, when it comes to inventions and innovations, electronics play a huge role. And due to these reasons, electronics hold huge importance in today’s world.
Application of Electronics in Different Fields
The devices and equipment meant for daily use are known as customer electronics; this industry is widely applicable to the common people. Some of its applications included office gadgets like computers, scanners, calculators, FAX machines, projectors etc.
It also includes home appliances like washing machines, refrigerators, microwaves, TVs, vacuum cleaners, video games, loudspeakers etc. and some advanced storage devices such as HDD jukebox, DVDs etc.
Industrial applications of electronics
Electronics engineering has a huge impact on the smooth functioning of the industries as it is used in various systems, grids and processing units. For example, smart electric systems collect information from the communication technology department, and several machines use automation and motor control systems using electronics; also, it is used in extracting 3D images from 2D using image processing systems.
Robotics and artificial intelligence
Apart from image processing that involves computer graphics, electronic systems are also used in artificial intelligence and robotics technologies for inspection, navigation and assembly. Virtual reality and face gesture recognition are computer-based, and these developments have been possible because of electronics engineering.
For data recording and physiological analysis, advanced, sophisticated instruments are being developed using the latest technologies and electronics engineering, and these instruments are very useful in diagnosing diseases and for healing purposes.
Electronics play a vital role in the functioning of medical instruments; for instance, the stethoscope is used to listen to the inner sounds of the human or animal body, a glucose metre for checking sugar levels, a pacemaker for dropping and increasing heartbeat count and so on.
Defence and Aerospace
Electronics technology has been used extensively in the defence and aeronautical systems, which include missile launching systems, cockpit controllers, military radars, aircraft systems, rocket launchers for space and many more.
Electronics are widely used in the latest automobile technologies, like anti-collision units, anti-lock braking systems, traction controls, window regulators and several electronic control units.

Functions of Electronics
Following are the main functions that electronics tend to perform:
Rectification is the procedure that converts alternating current (AC) into direct current (DC). There are several electronic devices that can alter AC current into DC current with great ease as well as efficiency, which has several uses like electroplating, charging batteries etc.
Through the process of amplification, a weak signal can be reinforced, and this process can be very easily accomplished by electronic devices. Using an amplifier in a radio set so that it is heard more loudly is a good example of amplification.
When it comes to automatic control, electronic devices tend to have an extensive range of applications. For example, stabilisers are used to control the voltage across an air conditioner.
Electronic devices are also proficient in altering AC power to DC power of any specific frequency. And when these devices accomplish this particular function, they are commonly known as oscillators.
