Electrical Engineering

Do you get fascinated when you hear the names like Thomas Edison or Nikola Tesla or George Westinghouse or Guglielmo Marconi or Philo T Farnsworth? These are names of prominent pioneers in electrical engineering whose innovated ideas and concepts about electricity into practical devices and systems we use in our modern age like the electric bulb or the induction motor, the alternating current, radio television respectively.

Not only is the past innovation, in the modern scenario electrical engineering one of the fastest growing fields that involve a spectrum of the study and application of electricity and electronics. The most interesting branch of engineering you can put it as it engages the study of the computers, the electrical, the electronics and the communication. It deals with the generation, the transmission and the distribution of electricity.

What does an electrical engineer do?

An electrical engineer extends their expertise on a variety of projects in spaces like the computers, the robots, the cell phones, the radars, the cards, the navigation system, the wiring and lighting in a building and various other kinds of electrical systems. As an aspiring electrical engineer, you should start a profit from the scratch by defining what a new electronic is intended to do. After that designing the circuits to create a prototype and test whether it is working properly or not. Obviously, in the first go there are some hiccups that need to be fixed. It is the job of the electrical engineer to figure out the existing problems and make the product work.

Those keen on electrical engineering need to have a useful, sharp and analytic to look for each and every detail. You additionally need to have great adoption and getting a handle on force to recognize imaginative ideas. Aside from having great communication aptitudes you likewise need to have the nature of organizing as well as problem solving skills

Specialization to pick from

You can step forward to specialize in one or more of the subdivisions of electrical engineering. The most popular are Electronic Engineering which deals with the electronic circuits such as the inductors, the transistors, capacitors, etc. The field of Microelectronics Engineering is the design and the fabrication of the microelectronic circuit components. There are the Signal Processing Engineers dealing with analog or digital signals or the Power Engineers specializing in electrical devices such as transformers, generators, etc. Instrumentation engineering is the design of the measurement of pressure, temperature and flow. For this you need to have a deep understanding of physics. The designing of computer hardware, it’s the computer engineers who specialize in that subject.

Prospects you can ponder upon

Electrical engineers are in much demand in hydroelectric power plants, atomic power stations, natural gas plants, thermal power station, petroleum sector and steel plants.. For a fresh graduate a starting salary of 3-5 lac p.a in usually on offer while an experienced candidate it’s not less than 80,000 to 1.25 that you will certainly draw each month. In the private organization the pay package is much better as compared to the government sector. In the public sector you are paid only Rs.30,000- Rs.40,000 per month.
