Electrical engineering is the largest technological filed in the world. The field offers educational and research opportunities in electronics, photonics, and nanotechnology; sensors, computers, and networking; and communication and control, signal and image processing. Competent electrical engineers have vast expertise in design and development of one or more careers of the discipline: telephone networks and switching systems, receivers and transmitters of radio, television and communication systems, generation and distribution of power, computer systems among others (Chen, 123).
Electrical engineers implement, test, install and maintain large-scale electronic devices and machinery used in manufacturing, generation of electric power and transmission. An electrical engineer uses computer-aided engineering and design programs (software) to do their assignments. He/she can apply principles and electrical engineering techniques to achieve his/her goals. For competence in the field, a bachelor’s degree and, at least, two years of experience mound them to be a respected individual in the field. He has the versatile knowledge of the obvious concepts, practices and engineering procedures with the electrical engineering field. Minimum supervision, Instructions and pre-established guidelines are the directives of his daily work.
Power engineers work in power systems engineering, a career in electrical engineering that deals with the generation, transmission, distribution and use of electrical power. Electrical machines associated with this field are generators, motors, and transformers. Power engineering uses theoretical basics from electrical engineering though some power engineers are referred as power engineers who do not qualify to work in these systems.
Communication and networking engineers design and evaluate the performance of communication systems, data networks of any kind including wireless and cellular, optical, ultra-little power, cyber-physical systems and data center networks. These experts use methods by analyzing and refining the existing approaches to developing new devices. A communication engineer is mainly concerned with the efficient transmission of information through noisy media. These channels apply in cellular radio systems, satellite technology, magnetic and optical recording systems. A network engineer designs protocols and algorisms to permit effective utilization and access to communication infrastructure like the internet, cellular radio network, packet switching, local area networks, and peer-to-peer network sharing among others.
Signal processing engineers perform their work in multimedia information centers to convert analog signals from speech, music, videos into digital form. These engineers manipulate the signals by the use of digital processing techniques on computers. The technique is applied in biomedical engineering, bioinformatics, video processing systems in stereo equipment and iPods. The refined signal processing electrical engineers are employed by multinational companies like Apple Inc., Microsoft, Agilent, Bose, and Spectrum among others. Control engineers work under electrical engineering to design systems of desirable behavior. Sensors are employed to measure the output functionality of a device under control and the feedback received by actuators that correct the input towards the desired performance.
Instrumentation engineering deals with the design of instruments to measure physical quantities like pressure, temperature, humidity among others. Instrumentation engineering deals with design and implementation of transducers. Well-designed and -developed transducers employ the use of electrical principles. Instrumentation engineers, therefore, need adequate knowledge and expertise in electricity, electronics, and electromagnetism, principles of electrical engineering. Among other electrical engineering concepts used in control, engineering is engineering graphics, communication skills, thermodynamics, semiconductor devices, electromagnetic fields, and electrical machines.
Lastly, electrical engineering has stood as the strongest field with great advancements and innovations. Two decades down the line, the world has experienced technological advancements successfully driven by electrical engineering. The world appreciates the work of electrical engineers as well.
