11012017-JC-01.qxd 1/10/2017 5:27 PM Page 1 c m y b CHANDIGARH | WEDNESDAY | 11 JANUARY 2017 Before choosing any branch of engineering it is necessary to understand the subtle differences between the seemingly similar disciplines ELECTRICAL ENGINEERING (EE) & ELECTRONICS AND ELECTRICAL ENGINEERING (EEE) GAURI CHHABRA Both these fields of engineering seem very similar but there are clear cut differences between them. Electrical engineering deals with the generation of electricity by various means like thermal, tidal, solar or hydro, which can be used by electrical motors, vacuum cleaners, lamps, submersible motors. Simply put, it deals with the method of producing electricity, the different means of production, the production or manufacturing machine that uses electricity, electric measuring instruments.. On the other hand, Electronics Engineering deals with the development and application of devices that use the flow of electrons in gaseous and vacuum form in semiconductor media. While the latter deals with the study of electricity, power generation and electromagnetism, the former deals with the study of electrons. Electronics engineering is a branch that has evolved from Electrical engineering but is a broader field that deals with analog electronics, consumer electronics, embedded systems, digital electronics and power electronics. Sift andselect ISTOCK One field that has gone full circle over the past few years is Engineering. From a discipline that had just 4 offshoots like Mechanical, Chemical, Civil and Electrical, it has come a long way and encompasses many new branches. This has been due to the changing societal needs and technological advances. With so many branches available, students are always in a confusion so as what to choose. Some of them overlap with each other in many ways. Examples include the sets of engineering fields like Electrical Engineering (EE) and Electrical and Electronics Engineering (EEE), and Aeronautics and Avionics Engineering. Let us understand the subtle differences between these fields: AERONAUTICAL & AVIONICS ENGINEERING Aeronautical Engineering deals with the development of new technology in the field of aviation, space exploration and defence systems. It specialises in the designing, construction, development, testing, operation and maintenance of both commercial and military aircraft, spacecrafts and their components as well as satellites and missiles. The specialisations are in areas like structural design, navigational guidance and control systems, instrumentation and communication or production methods or it can be in a par- ticular product such as military aircraft, passenger planes, helicopters, satellites, rockets etc. Avionics is like electronics. It involves the navigation system of satellites, signal processing. It is a sub field of aeronautical engineering and deals with electronic systems that are used on aircraft, artificial satellites and space crafts.Basically, it deals with the systems that are required for the aircraft to work seamlessly. Electronics in aviation is avionics. Avionics can be defined as 'Electronic Equipment used in the air'. This simple definition touches virtually every aspect of a modern aircraft, from the Engine Computers to the Fly-by-Wire Flight Control System. COURSE CURRICULUM A common aeronautics programme includes an introduction to the history of both atmospheric and space flight, including the basic elements of aerodynamics, fluid mechanics, rocket propulsion, launch systems, and thermodynamics. Advanced courses include aviation law and mechanical diagnostics. The Avionics curriculum includes a number of core Electronics and Electrical subjects like Control Systems, Digital Electronics, COURSE CURRICULUM Communication, Computer systems and all other associated subjects. In addition to courses in avionics, courses in Basic Sciences, Aerospace Systems, Economics, Management and Humanities are also there. JOB DUTIES Both the engineering branches differ in the job responsibilities that they offer. While it is the job of an aeronautical engineer to keep the aircraft airborne, continued on p3 As an EE student, you may learn about electrical machines, power systems, controls and instrumentation, power electronics and power systems operation and control. On the other hand, as an EEE student, you may learn about semiconductor devices, solid state physics, linear electron- DYAL SINGH COLLEGE TRUST SOCIETY, KARNAL Requires the following Staff For Dyal Singh Public School, Sector-7, Karnal PGT Physics (01) TGT English (01) - Preferably English Hons.

TRC-34346 c m y b ics, embedded systems, digital electronics, and advanced electronics. When the course of electrical engineering is merged with a few core subjects of electronics engineering, it results in a branch known as electrical and electronics engineering. This is done to increase the knowledge of electrical engineers in areas like digital and analog electronics, microprocessors, embedded systems, communication and in signal processing. The base branch is electrical, but the difference is that the electrical and electronics engineering course is not purely electrical, but has a few subjects from the electronic engineering course. Some companies specifically request electrical engineers, but most will take in electrical and electronics engineering graduates as well. Some exams like the Engineering Services Examination (ESE) only have an option of electrical and not electrical and electronics engineering. JOB DUTIES The work of electrical and electronics engineers is often similar. Both use engineering and design software and equipment to carry out engineering tasks. Electrical engineers typically design new ways to use electrical power to develop or improve products, perform detailed calculations to develop manufacturing, construction, and installation standards and specifications, direct the manufacture, installation, and testing of electrical equipment to ensure that products meet specifications and codes. They also investigate complaints from customers, evaluate problems, and recommend solutions and continued on p3
The Tribune, now published from Chandigarh, started publication on February 2, 1881, in Lahore (now in Pakistan). It was started by Sardar Dyal Singh Majithia, a public-spirited philanthropist, and is run by a trust comprising four eminent persons as trustees.
The Tribune, the largest selling daily in North India, publishes news and views without any bias or prejudice of any kind. Restraint and moderation, rather than agitational language and partisanship, are the hallmarks of the paper. It is an independent newspaper in the real sense of the term.
The English edition apart, the 133-year-old Tribune has two sister publications, Punjabi Tribune (in Punjabi) and Dainik Tribune (in Hindi).
