Basic Electronics Electronics Today Advances in electronics have given us pocket calculators, digital watches, heart pacemakers, computers for industry, commerce and scientific reach, automatically controlled production processes, instant viewing on our television screens of events n the other side of the world and a host of other applications. These have become possible largely because we have learned how to build complete circuits, containing thousands of electronic parts, on a tiny wafer of silicon no more than 5mm square and 0.5 mm thick. Microelectronics is concerned with these ‘densely populated’, miniaturized integrated circuits (ICS), or ‘chips’ as they are called, which are changing the way we live and work and challenging us to see that the changes are for the better. Chips are also used to control robots in factories, electric cookers, washing machines and traffic lights; they are the brains behind TV games and microcomputers; they form the hearts of machines for teaching spelling and arithmetic and can even be used to mix cocktails and recognize signatures! Today, electronics is being used to an ever-increasing extent in communication, control and computer systems as well as in domestic products and for medical care. In the first Industrial revolution, machines replaced muscles. In the second, now upon us, and brought about by microelectronics, brainpower is being replaced. Few areas of human activity are likely to escape. Resistance ”Resistance is anything that causes an opposition to the flow of electricity in a circuit. It is used to control the amount of voltage and/or amperage in a circuit. Everything in the circuit causes a resistance (even wire). It is measured in OHMS”.

... changing magnetic field, which passes through the secondary, thereby inducing a changing (alternating) voltage in the secondary. It is important that as much as possible of the magnetic field produced by the primary passes through the secondary. You should also notice that the induced voltage in the secondary is always of opposite polarity to the primary voltage (Lenz’s law). Too large a current in the transformer causes magnetic saturation of the core i.e. the magnetization of the core is a maximum and it is no longer able to follow changes of magnetizing current.

    Medicine and electronics are rapidly becoming a common partnership. Electronics and medicine has been around for over a hundred years. This application can be seen in early X-ray machines, as well as early doctors and healers who felt that electricity possessed something special that assisted the healing process of many illnesses and injuries. But it has not been the last forty to fifty years that the development and refinement of electricity as medical agent has occurred. Today the medical field can not imagine itself without the assistance of electricity and electronic components.

    Current systems are limited by the capability of sensors and actuators, as these are bulkier and less reliable than the microelectronic circuit. In a MEM system the sensors act as the ‘eyes’ and gather data about the environment. The microelectronic circuit, which is the ‘brain’, processes the data and accordingly controls the mechanical systems, the ‘arms’ of the MEMS, to modify the environment suitably. The electronics on the MEMS are manufactured using IC techniques while micro machining techniques are used to produce the mechanical and electromechanical parts.

    In the past few decades, one field of engineering in particular has stood out in terms of development and commercialisation; and that is electronics and computation. In 1965, when Moore’s Law was first established (Gordon E. Moore, 1965: "Cramming more components onto integrated circuits"), it was stated that the number of transistors (an electronic component according to which the processing and memory capabilities of a microchip is measured) would double every 2 years. This prediction held true even when man ushered in the new millennium. We have gone from computers that could perform one calculation in one second to a super-computer (the one at Oak Ridge National Lab) that can perform 1 quadrillion (1015) mathematical calculations per second. Thus, it is only obvious that this field would also have s...

    Electrical Engineers research, develop, design, and test electronic components, products, and systems for commercial, industrial, medical, military, and scientific applications (Cosgrove 749). They are concerned with devices that use small amounts of electricity that make up electronic components such as integrated circuits and microprocessors. By applying principles and techniques of electronic engineering they design, develop, and manufacture products such as computers, telephones, radios, and stereo systems (EGOE, 121). Electrical engineers touch everyone lives through the things they have designed or created. Electrical engineers have invented the lights in your house, the television, the stereo, the telephone, computers, and even your doctor’s blood pressure gauge (Stine 300).

Various levels of government employ civil engineers to do many of the same things done in private industry, except that the government-employed civil engineers may also inspect projects to be sure that they comply with regulations. Civil engineers generally work indoors in offices. However, they sometimes spend time outdoors at construction sites so they can monitor operations or solve problems at the site. Occasionally, civil engineers travel abroad to work on large engineering projects in other countries.
