Present And Future Of Electrical Engineering

Present And Future Of Electrical engineering scienceABSTRACTThe report is any about the by, fork out and the prediction of the futurity of galvanizing engineering in the tree branch of electronics which coquettes an important role in the improvement of electronic devices as well as the newborn technology, electronic engineering is a broad and ch allenging discipline because it is composed of antithetic kinds of electrical components such(prenominal) as electron tube, junction transistors, integrated circuits etc, thitherfore from all these electronic components the most vital components argon transistors as they have awe-inspiring characteristics comp atomic number 18d to an other(prenominal) components, transistor sizing is the most challenging when electronic engineers stir up to design thing like computers, electronic machine etc. basically transistors make electronics engineering to run much efficient when it comes to the production of electrical appliances bec ause from the past until nowadays, the usage of transistors had been increasing rapidly which shows that electronic engineers always makes manners become easier.1. INTRODUCTIONElectronic engineering in the past was non interesting because during that time it was hard to all overturn electronic material because in that respect was scarcity of resources that was victorious control over humans life. Electronics today is taking a lead because the economy and edict benefits from electronic engineering, as this is seen by anyone living on this planet. Many companies use electrical appliances such as computers, laptops, telephones etc. which lead to a good profit to their companies and thus this prove in a huge growth of the economy worldwide. Electronic components ar more than easily to be improved and this predicts that in the future things like plasma, laptops, internet atomic number 18 going to disappear because the electronics creates new technological devices any second and the way electronic engineering functions create hope of amaze changes that people cleverness not believe because things such as mortalal identity documents for the next eld go out be regarded as use slight papers. The society also benefits from electronic engineering because nowadays legion(predicate) health go uses electronics for example such X-rays and other electronics devices to detect for other diseases. Professional electronic engineers have good ethics because they also create strong educational activities by creating fair regulations that must be followed strictly to ensure that certificate is sustained towards peoples life.2. ELECTRONIC ENGINEERING CHARACTERITICSElectronic engineering is a branch of electrical engineering that deals with the implementation of applications, principles and algorithms by using non linear and diligent electrical components such as transistors, diodes and integrated circuits to produce electronic machines, televisions etc which i s more related to other field, for example radio engineering, telecommunication, control system and some(prenominal) other 1, 2.The transistors are the best electronic components that has become more multipurpose after they had been modify and transistors have several(predicate) function because of their size. They have different physical characteristics.2.1. Design and application of transistors in circuitsTransistors whitethorn have N-P-N or P-N-P structure which function as a switch both N-P-N transistors and P-N-P transistors consists of triplet regions collector, base and emitter. The base is the transistors main lead, without it, the transistor wont function, the collector is the supreme lead and the emitter is the negative lead. Therefore the N-P-N and other transistors are may be employ to control the flow of electrical current, occasion flow with the transistors from the power supply to the relay controlling the flow of electricity. Sometimes NPN transistors may us ually work as amplifiers by controlling large substance of current 3. Figure is on the appendix.2.2. Electronic componentsThere are many electronics that are widely use in electronic engineering to invert special electrical appliances. Symbols of some electronic components are re certifyed on the appendix.3. BACKGROUND OF ELECTRONIC ENGINEERING3.1. The past of electronicsElectronic engineering has win from technological improvements in the telegraph industry long time past in the late 19th century , Transistor is a known electronic component that is inverted in 1948 at the Bell anticipate Laboratories followed by integrated circuits in 1960, electronics is often considerable to have started when lee De Forest inverted the first vacuum tube in 1907 in spite of appearance 10 years, all of his electronic device was effectuate in radio, transmittance and receivers as well as system for long distances telephone cells 1, 2,electronic engineering was interesting because many thing s that are inverted during the 19th century are now improved to produce better materials that are very useful. Electronics play a signifi notifyt role when it comes to telecommunications because the beginning of electronics is more likely found on communication and it is also ameliorate because after the invention of radio, telegraph and other past electronics appliances the first purely electronic television is inverted in 1928 by Philo Farnsworth 2, and so this trend shows accurately that electronics always sift to progress from generation to another. During 1930s television had become more fashionable because it was recognized by millions of people to the best thing that was transferring information easily.During the past the computers that was inverted they were not programmed like the one that are being used now because they were very big and it hard to find because they only found at the laboratory of High institution and these computers was using big transistors that was storing less resources, therefore the most benefit from early computers is that they were better in ground of information transmission when compared to televisions. During the First realism War electronic applications had assay to play a vital role by creating electronic weapons for demur but the most successful electronics weapons are the one that was produced when Second World War take place5. Hence electronics had created a wonderful social sentience by providing people with strong electronic weapons to protect their life against their enemies.3.2. The present of electronicsElectronic engineering nowadays is a challenging field because there is a lot of competency for producing desirable electrical appliances which benefit the firm world. Electronic engineering is the best because many things that are being used all over the world to create peace, economic growth, excitement and employments are produced by electronic engineers. Information technology today is based on elec tronics because information is transferred from one place to another by using electronic materials such as cell phones, digital computers, advanced television such as plasma and other useful electrical appliances, therefore all of this benefit the country because it maintain peoples rights. Electronics is more useful for health service and educational purpose because today at universities they are using computers, power point during the lecture time and this help students to adapt, gain knowledge and skills in the electronic and technological environment. People all over the world are getting proper health care because there is variety of electronic applications on medicine e.g. X-rays, Ultrasound detectors, medical research and expands other diagnostic test which save human lives.Since the invention of radio television in the past other previous century the electronics industry has been increasing drastically with the beginning of computer technologies and cell phones the electron ics industry is regarded as the world largest and alacritous growing manufacturing industry. Therefore this flowing of electronics it release hazardous material that see the environment because when electric product become cheaper they tend to rapidly become more useless and some of these materials are dumped everywhere which lead to taint 6.4. THE PREDICTION OF THE FUTURE OF ELECTRONIC ENGINEERINGElectronic engineering provide always proceed to develop amazing things because educational level of electronics is improving each year which means that the economy will succeed more toward the following years because many people who are studying will invert new things that can become more useful than the present electronics devices. Technology is also faced with a huge change because electronic engineers are always trying to improve their skills. Cars the next following years they might use electronic components and electricity to move because petrol and other oils are regarded as dan gerous pollutant on the environment. Electronic engineering it might be bad when it comes to domestic employment because the many things that are created by electrical engineers makes life easier to a specific person even other professionals might lose their jobs because the engineers work it shows accurately that one day an electronic doctor can be inverted to save doctors from their work because other disease might infect during the working times. Therefore any person must try to be preparing for the next electronic generation because new desirable things are coming such as cell phones that can be used to drive cars. Laptops will be replaced by electronic engineers because they are big when compared to cell phones.4.1. THE TREND OF ELETRONIC ENGINEERINGThe diagrams representing the trend of electronic engineering5. CONCLUSIONElectronic engineering in the past was lamentable but it has evolved rapidly. Nowadays people are used to electronic systems, therefore this shows accurately that electrical engineering as whole it will get over toward the next four years because without electrical engineers lot of things will disappear like a mist for example the economy depends on electronics to attain its profit which means that when electronics drop the whole process all over the world will subside resulting in lack of employment, poor health care and other technological system will disappear. Electronics for the next xx years it might program people to function as electronics because the foundation garment has already began by computers e.g. people are using computers to improve their thought capacity and to get lot of information. Really electronics is the best thing that hold still for peoples intelligence because amazing things are taking place because of electronics e.g. the night is changed by lights which symbolise that everything it might be created by electronic devices.6.
