There are many similarities though also differences, between electrical and electronics engineering. In earlier years electronics engineering was known as "low-voltage' and electrical engineering as "high-voltage'. This classification is not correct or relevant any more. The difference lies in terms of information associated with electronics engineering and electrical energy that goes together with electrical engineering. With the above-mentioned as basis we can now look at what electrical and electronics engineering exactly are.
Electronic engineering :
Electronic engineering is that branch of engineering that has the specific goal of extending and supplementing the human senses and skills. It has to do with the obtainment, assimilation, control, transmission and distribution of information. Examples of electronic engineering are as follows:
» The use of an infra-red camera to "see" in the dark - an example of obtaining information. Phenomena that cannot be observed by humans, are transformed by electronic technology to observable phenomena.
» The use of computers to solve complicated problems and to assimilate signals assimilation of information.
» The control of mechanical and chemical processes through electronic systems control of information.
» International telephone conversations and video phones - transference of information.
» Mass media such as radio and television distribution of information.

Electrical engineering :
Electrical engineering is a wide field of study, which comprises all aspects of energy systems. It has to do with the generation, distribution and optimal application of electrical energy. Examples of these are:
» Thermic coal power-stations - here chemical energy is transformed to electrical energy - an example of the generation of electrical energy.
» The use of sun cells and wind-chargers to transform wind and sun energy into electrical energy - two examples of alternative ways to generate electrical energy .
» Transmission lines that cross the country, substations and eventually the separation box in a residence - distribution of electrical energy.
Just think for a moment how your day would be during a total power failure - this will give you a good idea of how electrical energy is applied to benefit all people. Even for those who do not have electricity at home it will be easy to see the advantages of electrification.
New technologies such as new materials, super computers, super-wiring and driving electronics are responsible for great innovations / strides in electrical energy techniques.
Electrical and electronic engineers are busy with the fulfilment of a phase (or phases) of the engineering process, especially with relation to the electrical and electronic related disciplines. This process comprises various aspects including studying, problem formulation, setting up specifications, pre-studies and analysis, design, simulation, research, development, testing, realisation, marketing, maintenance of electrical and electronic components, subsystems and systems. Electrical and electronic engineers are not necessarily involved with all the phases mentioned above, but usually specialise in one or more.
Within electrical and electronic engineering there are various disciplines in which the engineer can specialise. This includes electromagnetism, energy systems, computer engineering, bio-engineering, electrical machinery, signal assimilation, telecommunication, control systems, photonics, acoustics and micro-electronics. Many engineers are in management positions where they, to some extent do technical engineering work.
Electronic and electrical engineers typically work in offices or design centres. Depending on the nature of the work, the engineers usually spend a lot of time in the laboratory. The electrical engineers frequently find themselves in large constructions and / or installations such as power-stations. The nature and range of modern electrical and electronic engineering are such that practising engineers are usually always close to a computer.

Requirements
What kind of personality do I need? The electrical and electronic engineer should have the following characteristics: independent thoughts, an urgency to create, imagination and vision, above-average intelligence and a keenness to learn, combined with logical reasoning. The engineer must be capable of identifying a problem and must then try to find the best solution as fast as possible and at the lowest cost. Sometimes the optimum solution requires unlogical thinking. They must also have a aptitude and a liking for Mathematics, be innovative and have the potential to work independently, as well as part of a team.
Where can I work?
The electronic and electrical industries are nowadays the fastest growing. Electrical and electronic engineers work in a wide spectrum of organisations and firms. This includes private consultation firms and development laboratories, large and small private companies involved with design, development, production and marketing of electronic systems, subsystems and components of products, as well as government and semigovernment organisations.
Can I work for myself in this occupation?
Electrical and electronic engineers are being trained to see themselves not only as potential employees, but also as potential employers. By becoming entrepreneurs they can create a better society through the creation of jobs. Through the use of modern technology the electrical or electronic entrepreneur can compete on the international market. Exports, surely the most important form of creating prosperity for a country, can be affected. Another potential market for the young entrepreneur is import replacement.
