Question

What is Electronics?

Answer 1

Hint:In this problem we will define electronics, its area of application, advantages and limitations.
We will cover all the areas where we are using the application of electronics in our day to day life.
Therefore, no calculation part of this problem, only theoretical definitions will be discussed

Complete step by step solution:
Electronics is the branch of science and technology ,which deals with the electrical circuits and equipment like diodes, transistors and relays. It is the study of how to control flow of electrons . Electronics is all related to Physics and Electrical engineering .

Electronics is mainly divided into two categories :
-Communication system and control system .

Communication system : In which input is given signal is processed and the output is given ,like for example signals received in radar system , signals of our cell phones, signals of dish TV’s .

Control systems: In which controlling and monitoring of the system is done using electronics applications like controlling of panels in the power stations, power houses (where generation of electricity takes place) .

Electronics has various parts like analog and digital electronics.

-Analog electronics: Analog electronics is one in which the signal is a continuous waveform and is available throughout the processing. For example, our wall clocks, mercury thermometer.

-Digital electronics: digital electronics is the part of electronics where the signal is available in discrete form. Like digital watches ,digital thermometer .
Everyday , we are using applications of electronics ,right from morning till our sleeping all the gadgets ,instruments we use everyday have application of electronics in it. For example, the Induction heater we use in the kitchen, microwave ovens, our mobile phones , watches , alarm clock ,music system ,laptop ,desktop ,remote of the car , Television , ear phones , glucometer , fridge ,washing machine ,hair dryer .

Note:
All the gadgets we are using have made our life very simple , but these have a very bad impact on our health too, on our social lives . All the electronics equipment we are using sends out radiation which passes from within the human body which damages various tissues in our brain which leads to various sleeping disorders, makes us addictive , lazy and over reliant.
