Electrical and electronic engineers work at the forefront of practical technology, improving the devices and systems we use every day.
From solar-energy systems to mobile phones, we innovate to meet society's communication, tech and energy needs. Electricity is integral to modern life - power generation, transport, medicine, quantum information, computing, artificial intelligence, cryptography, communications, the list is endless.
So what distinguishes electrical from electronic? Put simply, electrical engineers deal with the supply and flow of power; electronic engineers create the electronic devices we use every day.
Both fields focus on real-world applications. If you are excited by maths and science, love technology and its potential benefits for society, this is the course for you. Research is at the heart of our mission, hence our international reputation. It informs our teaching and underpins our economic role in the region and collaborations across the world.
Without electrical energy, there would be no broadcasting and television systems, no telephone communication or telegraphy. In order to arrange automatic sequences of operation in production, devices of control an regulation engineering are required which, today, are driven almost exclusively by electrical energy. Table 1. The consumption of electrical energy by the various branches of economy is quite different.
The chemical industry and metallurgy have a particularly high consumption. For the production of the electrical conductor materials electrolytic copper and aluminium, very large amounts of electrical energy are required.
For this purpose, considerable amounts of primary energy carriers such as coal, petroleum or natural gas must be provided. All over the world, a reduction of the resources of primary energy carriers takes place. At the same time, their prices have been increased continuously. Water power is not in all countries available to a sufficient degree. Radio engineering emerged from electronic principles leading to the advancement of communication through commercial radio, radar and televise information.
The advancements in electronics have resulted in the development of numerous commercial radios, computers, television and microprocessors. Microelectronics presents a field that is quickly gaining popularity leading to the microfabrication of minimal electronic circuit components that are used in integrated circuits. The primary microelectronic components are developed through semiconductor transistors; however, all the primary electronic components can be developed at a microscopic level Cullis, Electricity presented a subject of primary interest since the early 17th century.
In the 19th century, there was intensified research in the electrical engineering field leading to notable developments in the field. For instance, George Ohm covered the concept of potential difference and electrical current whereas Michael Faraday discovered the concept of electromagnetic induction Jones, In the 19th century, electrical engineering became a profession. The global electric telegraph was formulated by practitioners and the initial electrical engineering institutions were created, particularly in the United States and the United Kingdom.
This resulted in evident prospects of the possible transformations that would result from the adoption of electricity. By the end of the 19th century, electrical engineering had transformed the world through the introduction of different electrical components that enhanced rapid communication and transport through the creation of submarine cables, landlines and wireless telegraphs Jones, In , Hull Albert was noted for his contribution in electrical engineering through the development of the cathode ray tube, which formed a portion of the oscilloscope, a primary component for the development of the electronic television.
Moreover, Fleming John also invented the initial radio tube, referred to as the diode whereas the amplifier tuber was developed in by Robert Leiden Ward, These developments have been applied in modern electrical engineering advancements facilitating the development of various output devices such as phones, televisions, and computers.
Consequently, modern electrical engineering has applied varying electrical principles to develop various devices of communication and entertainment. The practical evolution in the electrical engineering field prompted the development of units of measurement.
This resulted into the international standardization of measurements through the development of volts, coulombs, ampere, henry, and farad. In , there was an international conference that was held in Chicago, which determined the need for standardization in the electrical engineering field to ensure constant communication with other professionals Jones, The publication and adoption of these standards has resulted in different advances in the electrical engineering field since the various standardized forms were acknowledged in different legislations in nations all over the world.
An electrical engineer finds ways to innovate existing systems. One of which is to provide efficient energy distribution in the safest way possible especially for the end user. An electrical engineer makes sure that the energy circulating inside a building is safe. Electrical engineers also assure that electrical equipment are safe and efficient especially those that are in constant interaction with a living thing. They assure that the load is properly monitored and make sure power interruption is minimized.
Life in the modern world without electricity is unthinkable. The simplest realization is that without electricity, we would still be walking in the dark night with gas lamps and other harmful sources of energy. With the increasing industrialization of electricity, shops, offices, streets, and a number of different spaces rely on electrical energy to run. Man has become more productive since electricity was industrialized.
Without the innovations of these electrical engineers, there will be no more efficient machines and modes of transportation, no mobile devices, no conducive ventilation, no food preservation, no broadcasting and television systems, etc. Many advancements in medical technology are credited to electrical engineers. Success rates in the way doctors treat patients have been growing ever since.
With this, life expectancy of an average human being increased. The world has become more connected. Transportation has also improved. People can communicate and travel to different parts of the world much easier with these advancements owed to electrical engineering.
Humans have been able to send people to space. There are no aspects of the world today that is not affected by the work of electrical engineering. Basically, without electrical engineers, the world is stuck in the dark, and the world will just be sitting there outside wondering what it is like to touch the stars. One of the primary advancements in the electrical engineering field was the introduction of the first programmable computer in The Z3 presented a programmable computer that employed electromechanical sections Maxfield, In , the first functional, digital, electronic and programmable computer was introduced resulting in the introduction of the computer era.
