You are use electronics in your daily life from every small object to a big machine. The device by which you are reading this article is also a part of electronics. Electronics is a vast field that contains a huge amount of components like conductors, switches, circuits, diodes, processors, inductors, resistors, etc. All these components have important features to develop this field to more extant. Simply, when we study charges, current, electric or magnetic field, etc. actually we are working with electronics.
Electronics is a part or branch of science in physics and technology portion. This branch of technology deals with some equipment like resistors. Conductors, semiconductors, circuits, and chips in which there is the motion of the charge are included. This innovation is most important in engineering to handle various tasks and operate and operate machines.
As electronics is a field in which we study or manage the flow of electrons. We have studied that electric current is a flow of charges and this is the main component of electronics. We can see in our daily use that every appliance is powered or managed with help of electric current and Integrated circuits. These integrated circuits and chips work when there is a flow of charges in them.
Electronic has been known for many centuries. The first time use of electronic words was by Luigi Galvani in 1792 when he showed the presence of electricity on the body of animals. He experimented on frogs. After that, Charles Coulomb add his Coulomb’s Law of Electro-static in 1799. Also, in the same year, Italian scientist Alessandro Volta invented a battery. In 1827, Ohm’s law was proposed. Then, Thomas Alva Edison invented the electric bulb.
If we analyze the innovations in circuits and chips. The first step was taken by J A Flaming when he invented the vacuum diode in 1897. This invention by Fleming encouraged many other scientists to invent the field of Electronics. During WW1, the era of the diode was at its peak and the triode was used by the military for sending signals. In 1948, the invention of the transistor took place and replace the diode or triode. These transistors worked until new technology was not invented. In 1958, the introduction of Integrated Chips changed everything, like speed, cost, power consumption, etc Thus, IC become so popular in the world of chips and developed for microprocessors.
Electronics is a vital part of our life. At present, we can see have lots of electrical appliances in our home for daily activities and to make life comfortable. Mostly, appliances are based on some important inventions.
The invention of the electric charge is the most important in electronics. The charge was discovered by Luigi Galvani in 1792.
The discovery of magnetic field due to electric current. This phenomenon was discovered by Hans Christian Oersted in 1820.
The theory of resistance in a conductor was introduced by George Simons Ohm in 1827 when he proposed Ohm’s law to determine the relationship between current, voltage, and resistance.
The invention of electromagnetic induction was proposed by Michal faraday in 1831. This discovery leads to many new inventions like motors, generators, etc.
The invention of electromagnetic field which is the base of our modern communication system in invented by James Maxwell.
The invention of the Internet which changed the world completely was invented in 1960 however, the developed version of the internet was launched by Tim- Brener Lee in 1980.
The discovery of the Alternate Current is quite crucial for electronics and it was invented by Nikola Tesla.
The innovation of the camera and music system was also a breakthrough in the field of electronics for entertainment purposes. The electronic camera was invented in 1975.
The development of IC and transistors completely changed the way of switching and create a way for the invention of digital devices.
The use of electricity for lighting purposes is very important. In most regions of the world, people title electricity with light in their local language. The electric bulb was invented by Thomas Alva Edison around 1850.
Electronics are very important in every field due to their multi-functional property. The same motion of charge can do lots of tasks. Here, are some important functions of electronics.
Control − Control and management are very important in every field. We cannot use any device without controlling when there is proper visibility then we have to turn OFF the light bulb. Thus, we can use transistors and IC for automatic switching of electronic devices like refrigerators turn OFF automatically when there is no need for more cooling, and washing machines also turn the motor OFF when the clothes are completely washed for some time.
Amplification − When the signal is weak and unable to travel a long targeted distance we have to modify it. Thus we can amplify it with the help of an amplifier to enhance the quality and range of the signal. A general example of amplification is a radio which is fitted with an amplifier to make the information clear.
Conversion − Sometimes we have a different form of energy like mechanical or light, so we can convert it into any form of energy with the help of electric devices. The light bulb can change electricity into light energy. . Moreover, a motor can convert electric energy into mechanical energy.
Rectification − When we have an AC source of power but we have to use it for DCpowered appliances then we use it to rectify it with the help of a rectifier in the process of rectification. Also, the DC mode of current is more useful than the AC, it can be stored for a long time in Batteries.
In simple words, we can say that electronics has application in every field of life. There is no point or task which has no application of electronics. In the below bullet points we are going to discuss the important fields of life which are using electronics.
As electricity can convert one form of energy into another so industries use lots of mechanical tools which are powered by electricity to manage, manufacture, and packing of the products. Also, we use fans, coolers, and air conditioners to provide a comfortable surrounding for workers. All activities and processes are based on electronics.
Every piece of equipment at our home is powered by electronics. We use electronic appliances to reduce workload and make life comfortable, and entertaining.
Electronics are also used for transportation. Nowadays, technology innovation tends to replace traditional ICE-powered engines with eclectic cars and bikes. Moreover, the trains are completely electric-powered for the last few decades.
The advancement in the field of electronics also has a vital role in medical science. Every medical apparatus is powered by electronics like an X-ray machine, MRI, Thermometer, etc.
The internet is the main source of communication in the modern era. The devices like smartphones, PC, TVs, etc are based on the phenomena of amplification, rectification, and conversion of energy which are the function of electronics.
In conclusion, we can say that E is for electronics and E for essentials. This is the best two-word explanation of electronics in our daily life. So, day-by-day advancement in the field of electronics makes our relationship strong with it and also makes us more dependent on this field of physics.
Q1. What is a Transistor?
Ans. The transistor is electrical equipment. The base of the transistor is semi-conducting material. These are used in electrical devices for switching functions.
Q2. What is the difference between Electronics and electricity?
Ans. The difference between both is significant. As for spelling and sound both looks the same thing but in reality electronics is a branch of science in which we study the property, function, and uses of electricity. Whereas, electricity is the form of a charge when it is in motion.
Q3. What is the working principle of an Inverter?
Ans. The inverter is based on the technology that converts the DC into AC. As DC power is low so it uses the principle of amplification to make it a strong AC signal.
Q4. How does a bulb change the electric current into the light?
Ans. An electric bulb changes the electric current into light. It works on the principle of resistance which produces heat.. The bulb uses a high-quality resistor which produces a huge amount of heat into a glow.
Q5. What is the use of a Solar Panel?
Ans. The solar panels are built of photo-voltaic cells that convert light energy into electric energy.
