INTRODUCTION Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.

The electronic devices and their usages have

influenced our daily life in such a way that it is impossible to spend even a few hours without them. Right from the beginning of the day till the time we go to bed, we use a large number of electronic gadgets to simplify our work and to solve our problems. From small alarm watches to the complex computers, from mobile to the camcorders, from kitchen to toilet, from bedroom to office, everywhere electronic items can be seen.

APPLICATIONS OF ELECTRONICS

Aerospace industry –Today with advancement in electronic in the field of aerospace has open many impossible ways to humans. Electronics is widely used in aerospace such as Space shuttle, Satellite power supplies, aircraft power management. Even in commercial airlines there are hundreds of instruments which are used to

measure different physical factors like temperature, pressure, elevation, etc.Power electronics have huge contribution in spaces station and satellites. They all deal with power supply and management.

Medical –

The development of electronics, and particularly that of computers has made possible many of the technologies which made possible for a doctors to examine His patient. Many machines like x- ray, NMR etc which is the combination of different physics theorem and electronics. There are tremendous advancement of electronics in the field of medical sciences. There are few recent innovation which shows how

important is electronics – Robotic Check-Ups, Needle-Free Diabetes Care,   Electronic Aspirin, etc.

Automobile – Electronics are used in road vehicles, such as: carputers, telematics, in-car entertainment systems, etc. Initially electronics was used to

in cars to control engines.  The first electronic pieces were used to control engine functions and were referred to as engine control units (ECU). Later electronic with its huge demand it was further used in following parts of cars

1.Engine 2.Transmission3.Chassis 4.Active safety5.Driver assistance6.Passenger comfort7.Entertainment systems

Utility Systems – Electronics has also applications in utility systems. High voltage DC Transmission, Excitation systems, VAR compensation, Static

circuit breakers, fans and boiler feed pumps, supplementary energy systems(solar, wind)Due to the developments in power electronics field, the power transmission and distribution field faces tremendous changes such as HVDC transmission, Smart grid system. Conventional power transmission happens based on AC supply. It has a lot of disadvantages comparing with DC supply based power transmission. Few of the features of High voltage DC Transmission (HVDC) are given below:HVDC requires only two connectors. In case of AC transmission three connectors are mandatory. It leads to huge saving in the installation charges.When the transmission happens at high voltage DC supply.

Commercial –With advancement in electronics last few decades, electronics has also made its ways into commercial sector. Advertising, heating, air-conditioning power supplies, computer, office equipment, elevators, light dimmer, uninterruptible power supplies, central refrigeration all are simple application of electronics in commercial sector. With these simple commercial appliances electronics has made daily life much easier and better.

Agriculture - With increase in global warming electronics has proved very useful to solve these problems in of agriculture. Today many devices and system are builds with combination of electronics and different other techniques to monitor a crop. Like e-Agri

Sensors Centre and other sensor for sensing the crop above and below the land and also postharvest crop. These sensor monitor the crop quality as well as the needs for crop during agriculture. There are also several other electronic gadgets which are used for measuring the moisture level, nutrition level in soil and also salinity of soil.

Communication –  Electronic devices and systems are used for the acquisition or acceptance, processing, storage, display, analysis, protection,

disposition, and transfer of information.

Electronic devices and systems used in the transfer of ideas and perceptions;

Electronic sensors and sensory systems used in the acquisition of information devoid of semantic influence;

Electronic devices and systems intended to allow friendly forces to operate in hostile environments and to deny to hostile forces the effective use of electromagnetic resources.it is very useful we can play games such as CS go, GTA, prince of Persia.

Industrial - Arc and Industrial furnaces, blowers and fans, pumps and compressors, industrial lasers, transformer tap changers, rolling mills, textile mills, excavators, cement mills, welding. These are the various parts of industry where electronics appliances are used widely. Nowadays in some manufacturing industries and factories used robotics technology are used widely. Such as in manufacturing of cars.

Residential –There are also various electronic equipment which make our life easy and better. Such as air conditioner, cooking appliances, dryer, personal computer etc. These equipment make daily life easy. Nowadays, mobile phones are used by each and every person.

Military –Electronics devices and machinery are also widely in military. UAV and drones are some common aerial electronics machines which are used in the military for aerial attack as well as for monitoring. There are also some electronics equipment used in guns and airplanes which help soldiers to target his enemy during frontline war. Magnetic anomaly detector Night vision device, People sniffer, PNS Hameed, infrared detector and night vision camera etc. are some gadgets used by military.
