- Q: Equipment Used in the house.Room in the house___________Equipmenta. bathroomb. kitchenc. living roomd. bedroomgive the Equipment of room in the house
- You too eh? I've had to get 2 new tvs, a new computer, had my xbox 360 fixed twice, 2 new mp3 players, a new dvd player and a new alarm clock in the last 8 months. The electronics fairy has curseth me.
- Q: Can you actually save a decent amount of money by unplugging things like cable boxes, microwaves, etc.?I've taken to shutting things down when I leave for work, but there's really no way I'll be able to determine how much I'll save. If it's not significant enough I'd rather not bother - waiting for the cable to reboot is a pain!We have two cable boxes with associated TVs and DVDs that get shut down along with our clean air machines. Is it worth it?
- often a 15watt CFL will provide a similar quantity of light as a 60watt incandescent bulb and an excellent style of of the CFL's will final as long as 10 cases longer. i've got got here upon that greater decrease priced bulbs tend to burn out swifter than GE or Phillips. So interior the long-term you're able to shop on potential and changing bulbs. yet another attention to saving the two money and potential is changing lighting fixtures furnishings I even have 2 furnishings that have 6 candle bulbs and a gap gentle i'm going to be changing the two one in each and every of them with furnishings that take no greater beneficial than 3 low potential bulbs. I even have already replace 2 ceiling followers which had gentle kits that had 4 bulbs with a fan that has a delicate kit that takes a unmarried potential saver bulb.
- Q: electrical engineering
- use a non contact heat detector. fluke and many others make units that can sense the IR radiation at the terminal and determine the temperature from it.
- 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 will go to American in next month and I need to get some pieces of equipment e.gcamera,digital vedio,so I need someone canlet me know how much walt use in u.s.a .Because we use 210 walt in Hong Kong.I need to bring the adaptor or not.Chelsia Leung
- USA uses 120 volt, not 220 volt. You will need adaptors.
- Q: I need to make some electrical schematics up for some older equipment. What programs are available other than AutoCAD? Not wanting to spend the $$$ for AutoCAD at this time and I'd prefer not to use paper and pencil.Thanks.
- Search: electrical CAD several choices are available. AutoCAD is not very good for schematics.
- Q: I plan on starting college next September to study electrical electronic engineering, it's three years in college then moving onto university. In college I would be B Tech qualified and the awarding body is EAL. Is B Tech qualification good ?What Qualifications will I get out of university ?What's the difference between BEng and MEng ? Could an Electrical Engineer work on oil rigs ?
- It all depends on what you mean by electrical engineer. Do you mean someone who is hands on and performs wiring, repairs and installation, etc. or someone who sits mainly at a desk and designs electrical systems. If you mean the latter the the MEng is the golden standard qualification to enter into this career. However systems designers would be office / lab based and would be unlikely to get offshore. If you mean the former then a vocational HNC, preferably done as part of a modern apprenticeship would be the way to go. With this kind of route you could eventually work offshore repairing / maintaining equipment, however you would need to start at the bottom in an onshore industry sector and build up skills and experience before you could work offshore.
- Q: how we can design the power rating of any electrical equipment. as per my understanding only way is is to change the resistance of coil( winding if motor, filament if lamp).if it is correct then the equipment will be burn if resistance is low for low power rating. Eg. resistance of filament of 10 w lamp is lower than the resistance of 100 w. generally life of 10 w lamp is higher than 100 w. but in electrical point of view the life of high value of resistance equipment will be higher than the low value value of resistance. means, 10w bulb will glow longer time comparatively 100 w bulb. since 10 w bulb has high resistance , so this bulb's life should be higher than 100w bulb. can anyone explain how to design the power rating of any electrical equipment in line of other electrical parameters.
- The resistance of a heater or filament is is chosen to pass the required ampere load at the design voltage. Watts Amps x Volts.
- Q: If I decide to choose electrical engineering as my college major what would I be doing on a regular basis for my job?
- Hey Chocolate, I am an electrical engineer in the UK, currently working as a project engineer for large construction projects such as hospitals, schools, defence, nuclear plants, factories, etc . I used to work in the Steel works as electrical engineer previously. Electrical Engineering is the backbone of engineering but there are many different career paths for an electrical engineer. All electrical engineer role will inevitably involve specifications, schematics and drawings which you will need to understand and be able to advise/instruct others to work in accordance with them. It will also most likely involve man management on projects as well as materials and other resources. Man management can include in-house labour or sub-contracted. The most important aspect of an electrical engineer's role is undoubtedly Heath Safety. This is critical in todays engineering environment. You can see electricity so it is very easy for accidents to occur and someone die when working in and around electrical services and equipment. This is not just electricians and the like, this can involve all trades / specialist services who work near live electrical conductors. So as electrical engineer, you would be responsible for others, ensuring work is carried out to a high level and safely. This means implementation and management of permit to work systems as well as management of adequate electrical testing regimes and cooperation and integration with other engineering disciplines such as mechanical, instrumentation and controls, etc. I have only briefly mentioned some things here but there are many, many other electrical career paths for an engineer. It is all gonna boil down to what you have an interest in and what excites you because when you have that, it doesnt feel like a job and it aint so bad having to join the rat race for the 10 -12 hours every day. Hope this helps.
- Q: I paid taxes and homeowners fees for 15 years. There are no buildings on the land. Also had to pay for an electrical hookup, although no electrical equipment was installed.
- You need to clarify your question further. Did you deduct any of the expenses paid connected to the investment land you owned for 15 years? In tax year 2007 the long term capital gains tax federal is a whopping 5%. Figure your basis and subtract it from what you sold for; then mulitply it by 5%. Example.basis 10,000.sold for 15,000gain is 5,000.times 5%.$ 250.00 tax.
