Q: Do they design circets for the electricity? If not, what do they design?: There are many different areas of specialization in electrical engineering.

Q: i know that megger is used in marine.but how its been used and please give me other megger application in detailedthanks for answer: In electrical testing we megger equipment. A ac voltage 600 volts is induced one a piece of electrical equipment like a transformer and the impedance is measured. The megger measured AC resistance/impedance vs normal dc resistance that volt meter measure. The higher voltage gave a more accurate measure of impedance. Equipment with defective insulation, would have a lower impedance.

Q: I have been doing some research in which stocks i would like to invest in. Well i found this company called Raser Technologies. Supposedly they are a geothermal electrical power plant company. With Obama's environmental laws that he is passing, will this cause this stock to increase? i dont know a whole lot about stocks or about this company but if they step up as a major alternative energy companies then they should bring in a lot of profit seeing as their stocks are now only at2.27 a share. any information about this company or predictions for the future of other alternative energy companies would be greatly appreciated. I really think that with all the searching of alternative energy sources, this would be a great investment for the future when these companies step up.: Wow, okorder

Q: If this is maintained, but voltage changed from 480V to 240V, by what ratio will supply line losses change?: Power voltage x current Therefore current power/voltage. Thus, if power is constant at 2000kW current at 480 volts will be: I 2000,000/480 4166.67amps At 240 volts: I 2000,000/240 8333.33 amps However, line losses are current (squared) x resistance Thus the ratio will be 4166.67 (squared) / 8333.33 (squared), resistance remaining constant of course. I make that 0.25 (or 4, if you are thinking that way up!) That help?

Q: I need to know what object or whatever uses light energy that then leads onto electrical energy that then leads onto kinetic energy in order to work, what equipment does that? I said a Solar powered calculator but it was wrong so i'm really confused, could anyone help?:/: The calculator does not produce movement, kinetic energy. Although you could consider the flow of electric currents a form of KE. No good examples come to mind. Perhaps a toy auto powered by a solar cell. A cell phone charged by a solar cell, when it rings in the vibrate mode. (Vibrate mode is cause by a small motor rotating a weight)

Q: Are the different parts of an electrical distribution system connected in series or in parallel? Give the evidence. Give two reasons.: All equipment should get supply voltage same.So we have to connect all in parallel But to complete the circuit, we need Phase and neutral Bulbs, fans, washing machines, fridges are connected in parallel

Q: I'm a freshman in college in electrical engineering. I chose this major at random and so far, I hate it. I have no idea what people in my major CAN do, so when I go to job fairs, I look clueless to everyone there. The worst part is that I AM clueless. I've had companies ask me, what can you do for us? and I don't know what to tell them! Please help.: Engineering is all pretty much the same, regardless of what one builds. Consider mechanical engineering. One can either build cars or fix cars. Being able to design engines takes a master's degree at least. Fixing cars can be something done with a trade school Associates degree. This is basically the difference between electricians and electrical engineers. Obviously there are many more jobs for the electricians. There is commercial contracting or residential service or any combination of the two. Of course, you will spend your career wiring circuit breakers and very little else. To get an idea of what an actual electrical design engineer does, take apart anything electrical. All those little chips are entire circuit boards. The little metal legs are power inputs and signal inputs/outputs. Larger circuits are built up from the chips. One has to be able to read the data sheet on the chip and then be able to build a circuit around it. This is far more complicated than replacing blown fuses and explains why design engineers need masters degrees or (preferably) PHD's. If you like building things and are comitted enough to endure the many semesters of math and physics required (besides the electrical engineering itself) then design engineering is going to be both enjoyable and very profitable. Of course, becomming a technician first and then furthering one's education is another route to becomming an actual designer. Remember, besides science, economics is also an issue and education is incredibly expensive in America because people refuse to fund affordable public education with tax increases.

Q: I have been warned that some electrical equipment could possibly be damaged by chinese electrical systems.what voltage system does china use. is the supply unreliable and prone to spikes or surges etc.: Lithium batteries choose a particular charger as they are able to ignite if over charged. they additionally will fail if discharged under 3 volts or so. you may desire to income extra. Edit. confident, some lithium batteries are no longer rechargeable. have been given so used to those that are - from my interest of type plane - that I forgot that some are no longer. Had a glance- those are no longer very lifelike, those cells designed for calculators and so on. stable for purposes the place there is an rather low drain and you choose long existence. no longer a stable thought for motorcycle lamps/torches etc. some chinese language maker has in simple terms positioned those out devoid of concept for what occurs whilst the 1st set of batteries run out. For motorcycle lamps I reccommend lighting fixtures furniture that use AAA or AA batteries, and then decide for NIMH recheargeables - Eneloop type is stable. while you're going for lithium recharchegable then the voltages are all distinctive and the chargers are too. as quickly as you do flow above single cellular lithium chargers then there must be balancing circuitryotherwise there's a hearth threat/threat of cells death. have you ever been following the maximum up-to-date information on the Boeing airliner with lithium batteries ?

Q: After all, the whole point of ATEX certification is that it doesn't make a fire. One would think if you can safely use something in an explosive atmosphere you can use it on shabbos. By the same token a shabbos light should be safe to use in an explosive atmosphere.: When I was in fourth grade, the science teacher taught us the physics definition of work and explained how it differs from the everyday definition of work Much like that -- Jewish legal definitions of Hebrew words do not always line up perfectly with the everyday use of English words that aproximate them. With electrical items, the prohibition of fire is only one of the prohibitions to be aware of for Shabbat -- off the top of my head, there is also boneh (building) and bishul (cooking) On the reverse side -- your logic does not hold in even the most basic English definition. It is only the Karaites that believe there is a Shabbat prohibition of fire, the normative prohibition is on making fire and putting out fire -- thus, there are quite a few devices used on Shabbat that are straight forwardly on fire (well, heck -- just think of the candles themselves!!!) A Shabbat lamp is simply always on - but has some cover to keep the light from bothering. Hopefuly, this whole structure is well insulated (I don't know -- never used one)
