Amongst many fields of engineering, the most sought after field in which most of the students want to challenge their prowess in, is none other than Electrical Engineering. It is a field of engineering which is concerned with acquiring the theoretical and practical knowledge of electricity, electromagnetism and electronics. Since its inception, it has been sub-divided into many categories considering the diversification of fields and innovation being sprouting everywhere.
Some of the most well-known branches which have found the Electrical Engineering as their origin are
- power engineering,
- transmission engineering,
- system engineering and
- electronics engineering.
Electronics Engineering is the one which has been further sub-divided into
- Radio Frequency Systems,
- Remote Sensing Engineering,
- Signals Engineering and
All of these we mentioned above, are all the branches evolved from a single Electrical Engineering. Extending the idea of acquiring theoretical and practical knowledge, Electrical Engineering also deals with designing of electrical pieces of equipment and their installation at various sites is also done under the supervisory principles of Electrical Engineering.
History of Electrical Engineering:
So far the history of electrical engineering is concerned, it is not that much ancient as it dates back to 19th century. This field of engineering came into being with a groundbreaking invention made by John Fleming in 1904. He invented the thermo-ionic valve diode vacuum tube and thus laid the basis of modern day’s most opted field known as Electrical Engineering. This specialized vacuum tube acted as a current amplifier while on the output side, the scientist received a significantly increased input current. This experiment not only just originated electrical engineering but also laid the firm basis of working mechanism relating to electronics.
Earlier experiments in electricity involved working with batteries and static charges using primitive tools and pieces of equipment. With the advancement made in the field keeping Faraday’s Law as the basis, the world then was then introduced to a groundbreaking invention known by the name of electricity generator.
Following this invention made in 1904, the later breed of scientists then invented the radio, television, radar, the telephone and much more. Much advancement has been observed in mid-20th. Most of it was attributed to nothing else but transistor. It was then given a modified look in 1947 at Bell Labs by William Shockley and his team of associates. After doing much credible research in this field, William Shockley , John Bardeen and Walter Brattain were honored to be the recipients of the most prestigious award, The Nobel Prize in 1956. Some famous electrical engineers in history include Thomas Edison, Nikola Tesla, George Westinghouse, Guglielmo Marconi and Philo T. Farnsworth.
What do Electrical Engineers do:
According to the United States Bureau of Labor Statistics, the Electrical Engineers are entitled to
- designing a system,
- developing the designed system,
- testing the developed system under certain conditions and
- then deploying the system systematically.
Moreover, the electrical engineers are also employed to supervise the manufacturing process of various electrical equipment. It also includes the manufacturing of electrical pieces of equipment like electric motors, navigation and communication systems, power generation pieces of equipment and much more. In short, every single electricity-related gadget we use or wish to use, has its existence entirely beholden to electrical engineering. In points below, we are about to mention the tasks done by an Electrical Engineer.
Electrical Engineering tasks
- Electrical Engineers are entitled to write the code of quality testing of the devices being manufactured in order to check their durability. The destructive or non-destructive performance testing is also done by the electrical engineers.
- Electrical Engineers design various sophisticated electrical pieces of equipment with much precision and accuracy than before, via using the same basic components like coils, magnets, batteries, in individual form or combined form.
- With the help of Computer Aided Design systems, electrical engineers design various layouts of a circuit to deploy. A whole layout of a grid is also designed in the same software.
Latest Breakthroughs in Electrical Engineering:
- In the world of transistors, some high quality and super-efficient transistors have been introduced by the name of Gallium Nitride (GaN) transistors. These transistors are quite cheaper and better in performance from the traditional transistors in use.
- The efficiency of Light-Emitting Diode is getting a positive increment rate with every passing year and the day is not far when it will rule out every single fluorescent bulb.
- The Organic Light Emitting Diodes, are another great improvement towards a brighter future as they consume less power and can be used in the displays of cell phones and T.Vs.
- With the help of advanced high-quality notch sensors, electrical engineers are in search of such self-organizing networks which are comparatively cheaper to monitor and can be done with just a single command.
- The concept of super-capacitors was first introduced in 2005, while today the super capacitors are being used to deliver quite strong power surges to the machines being driven by them. These super-capacitor tubes are being manufactured from carbon-monoxide. The hybrid vehicles being introduced by Honda or Toyota, need a strong thrust for power to get started in the first place. This power is then provided via super-capacitors.
Electric Engineer Salary
This and even more startling advancements are being made by electrical engineers across the globe. We just have to remain updated and adapt ourselves to the dynamics of this ruthless world.
How much an Electrical Engineer Earns:
According to a report published in July 2014, the salary of a freshly graduated electrical engineer started from $54K to $110K. The salary of a masters degree holder electrical engineer amounted to be between the range from $74,500 to $109,000. And the salaries of top-notch, experienced electrical engineers were starting from $97,400 to $139,000.
Electrical Engineering, though being the newest amongst many engineering fields, is always welcoming the graduates. Its scope makes it more and more versatile and open to challenges most likely to be overcome by the fresh minds. Before you go for any other discipline, do remember to skim through the outline of Electrical Engineering course and then decide was it worth it?
