Electrical

Electricity is a general term encompassing a variety of phenomena resulting from the presence and flow of electric charge. These include many easily recognizable phenomena, such as lightning, static electricity, and the flow of electrical current in an electrical wire. In addition, electricity encompasses less familiar concepts such as the electromagnetic field and electromagnetic induction. The word is from the New Latin ēlectricus, "amber-like", coined in the year 1600 from the Greek ήλεκτρον (electron) meaning amber (hardened plant resin), because static electricity effects were produced classically by rubbing amber. Usage In general usage, the word "electricity" adequately refers to a number of physical effects. In scientific usage, however, the term is vague, and these related, but distinct, concepts are better identified by more precise terms:
The most common use of the word "electricity" is less precise. It refers to:
Electrical phenomena have been studied since antiquity, though advances in the science were not made until the seventeenth and eighteenth centuries. Practical applications for electricity however remained few, and it would not be until the late nineteenth century that engineers were able to put it to industrial and residential use. The rapid expansion in electrical technology at this time transformed industry and society. Electricity's extraordinary versatility as a source of energy means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation. Electrical power is the backbone of modern industrial society, and is expected to remain so for the foreseeable future. From Wikipedia under the

Q. I am intreasted in Electrical Engineering, could somone (preferably an electrical engineer) explain to me in detail what they do on an average day. Thanks alot! Asked by clint2134 - Tue Oct 14 18:37:07 2008 - - 3 Answers - 0 Comments A. Regular day in the life of a typical electrical engineer: 1. Wake up. 2. Drink coffee. 3. Go to the office. Sit in a cubicle. 4. Drink coffee. Maybe eat a donut. 5. Scribble some formulas on paper and run some calculations on the computer. 6. Get dragged into meetings with non-engineers...ugh! 7. Drink more coffee. 8. Go home. If I ever have one of those 'regular' days, I'll probably die or retire.

Q. I recently went into a century tel building and was VERY interested. Does that have anything to do with what an electrical intrumentation technician does? If not please explain to me the difference between some one that is an electrical instrumentation technician would do, and what someone that works at century tel would do. I know this is a lot but Im planning for a major, and after that a career. Thanks!!! Asked by Taylor R - Wed Dec 31 13:17:55 2008 - - 2 Answers - 0 Comments A. The main function of an instrument technician is to maintain the components that are used in controlling a process. The type of process would determine the type of instruments but commonly, pressures, temperatures, flows, levels etc are monitored by instruments and the information sent to a control system such as PLC. The control system will then make necessary changes to the process by things such as valves, gates, etc. In between may be transducers etc that are all part of the instrument technicians responsibility. I don't know what century tel do but you will find instrument technicians in any large process's such as oil, chemical, steel, power companies etc etc Answered by Poor one - Wed Dec 31 14:29:20 2008 From Yahoo Answer Search: "electrical" |
