What is Electronics | Components | Devices | Scope | Difference

The branch of engineering that deals with the flow of current through vacuum tubes, gas tubes, semiconductors, etc. is called electronics.

There are Two Types of Electronics Components

    1.  Active Component
    2.  passive component

Active Component – A component that requires a separate power source to run. Such as – Transistor, FET, TRIACs, SCRs, LEDs, etc.
Passive Component – Components that do not require a separate power source to run. Such as – Resistors, Capacitors, Inductors, Diodes.

Electronic devices

Devices through which the current generated by the flow of electrons flows are called electronic devices. Such as: different types of diodes, transistors, capacitors, transformers, etc.

Types of Electronic Devices

There are basically two types of electronic devices in terms of structure. E.g.

    • Bulb State Electronics
    • Solid State Electronics

Bulb State Electronics: The current generated by the flow of electrons through a vacuum tube or gas is called bulb state electronics.

Solid State Electronics: The current generated by the flow of electrons through a semiconductor is called solid state electronics.

Scope of Electronics

One of the major branches of electronics electrical engineering, the first electronic device was the thermionic valve or vacuum tube, in which the electrons scattered in the empty space and served as the main controller of innovations such as radio, television, radar and digital computers. The invention of the transistor in 1947 and the subsequent development of the Integrated Circuit (IC) revolutionized the field of electronics, all of which were based on earlier electron tube technology.

Modern electronic equipment is based on all the finer silicon chips that contain at least 10,000 electronic components. Such developments have helped to arrange electronic circuits in a more dense format and have helped to reduce the size of instruments from smaller to smaller. This has led to the creation of condensed miniature computers, advanced radars and direction or positioning systems, and other devices that use a large number of components.

The first use of electronics in the country began in 1930 with the establishment of radio stations and telephone exchanges and wireless communication. During World War II, wireless communication technology was further developed for military purposes. Examples of widely used electronic devices are wireless, television, audio-video cassette recorders and players, microwave ovens, wireless telephones, etc.

The Main Difference Between Electrical And Electronics

Learn Some Precautions Before Starting Work on Electronics

The fun of making your own device is different and if it is an electronic device then its fun is more. Those who have been successful in various types of projects, they must admit that each successful project fills the mind with an indescribable joy. At the same time, every failed project gives the motivation to start anew. This happiness or energy can instantly cause you to face a bad experience in the wake of a terrible accident. If you do not know the safety rules and do not follow them even though you know them.

There is a general safety rule for all electrical work that is internationally recognized and must be observed. Which will make it safer for the device to be operational during and after work. This safety is important to both you and the device you make. Many people go to work as a hobby or work very bravely or without following the safety rules. Better a poor horse than no horse at all. Any electronics work without safety rules must be discarded.

Here are some common safety rules that every electronics hobbyist must follow. Let’s know those rules a little.

1. The feet must wear sole shoes made of rubber or electrically conductive material.

2. The tester should be kept close at hand and should be checked by the tester at all times before going anywhere in the circuit with empty hands.

3. Rubber gloves should be worn on the hands.

4. The power line should be checked for proper grounding.

5. If you do not have experience, you should not work without the presence of an experienced person on a high voltage line or a line that uses electricity for all purposes.

6. Positive or live neurons in the line should never be sorted together.

7. No component can be reversed.

8. After making a circuit, after checking at least three times, if everything is found to be correct, then the connection should be given.

9. There should be a system to quickly disconnect the main line as well as use appropriate quality safety fuses.

10. A first aid box is very important (with a little cotton, bandage, antiseptic cream).

11. The tongue or shorts can never be used to check if there is a battery or line light.

12. Care should be taken to ensure that the cobalt produced during soldering does not go directly to the nose.

13. You have to be careful when working with sharp objects.

14. Before working, all the tools should be checked to see if they are working properly.

15. Sleep deprivation, tired body and sick state should be refrained from working.

16. You have to use quality parts without looking for cheap parts.

16. You have to work carefully all the time.

16. Do not allow any child to enter the workplace.

19. If you take the help of an inexperienced person, explain the helper in a good way before taking help and then start working.

20. When projecting high voltage, be careful not to touch any part of the body under any circumstances.

21. Safety goggles should be worn with clear colored eyes

22. Electrical lines should be used in series connections, as well as in conjunction with a separate circuit breaker line to ensure safety.

Remember- even if you don’t know anything about electricity, electricity is always ready to shock you. So do not go to show any kind of courage and magic.
