What is Engineering?

Engineering is defined as the branch of science and technology concerned with the designs, buildings, and use of engines, machines, and structures it is also defined as the action of employed artfully to bring something about.

Types of Engineering:

 

  • Electronics Engineering
  • Computer Engineering
  • Electrical Engineering
  • Mechanical Engineering
  • Civil Engineering
  • Chemical Engineering
  • Geo technical Engineering

 

Electrical Engineering:

Electrical engineering is Branch of Engineering which deals with technology of Electricity and the Electrical materials, power generations and transformations of Electrical energy.

Electrical engineers work on a wide range of components, devices and systems, from tiny microchips to huge power station generators. It’s have a broad field of technology and information’s in it. Engineering in fact is a term in which we reduces our burden and utilize the technology to overwrite our discomforts.

Early experiments with electricity included primitive batteries and static charges. However, the actual design, construction and manufacturing of useful devices and systems began with the implementation of Michael Faraday’s Law of Induction, which essentially states that the voltage in a circuit is proportional to the rate of change in the magnetic field through the circuit. This law applies to the basic principles of the electric generator, the electric motor and the transformer. The advent of the modern age is marked by the introduction of electricity to homes, businesses and industry, all of which were made possible by electrical engineers.

Some of the most prominent pioneers in electrical engineering include Thomas Edison (electric light bulb), George Westinghouse (alternating current), Nikola Tesla (induction motor), Guglielmo Marconi (radio) and Philo T. Farnsworth (television). These innovators turned ideas and concepts about electricity into practical devices and systems that ushered in the modern age.

Since its early beginnings, the field of electrical engineering has grown and branched out into a number of specialized categories, including power generation and transmission systems, motors, batteries and control systems. Electrical engineering also includes electronics, which has itself branched into an even greater number of subcategories, such as radio frequency (RF) systems, telecommunications, remote sensing, signal processing, digital circuits, instrumentation, audio, video and optoelectronics.

The field of electronics was born with the invention of the thermionic valve diode vacuum tube in 1904 by John Ambrose Fleming. The vacuum tube basically acts as a current amplifier by outputting a multiple of its input current. It was the foundation of all electronics, including radios, television and radar, until the mid-20th century. It was largely supplanted by the transistor, which was developed in 1947 at AT&T’s Bell Laboratories by William Shockley, John Bardeen and Walter Brattain, for which they received the 1956 Nobel Prize in physics.
