Q: I am going to be starting college soon and I would like some input to these two engineering majors. I know I want to pick one of these but I dont know which. I love building things but I also love tinkering with computers and technology. I've read that ECE has a better job outlook as well as a better salary. I think I might like ME because of the hands on although i think alot of it is designing on computers.[. I know I have time to decide in college. Any Help/Opinions??: In terms of jobs, opportunities, money they all are basically equal. The question is what type of problems do you like to solve. I went into Electrical because I aced those chapters in high school physics. Today I solved several problems. I had one phone conference. Help plan a project, work that was to be done, material needed, key people. I made several follow up phone calls to see where key equipment and what calculations were completed. I reviewed a arc flash study, spot checked by hand a few of the computer calculations. Programs a great, but garbage in garbage out. About a month ago I was out in the field, and my friend Chris had a problem. Chris may be a mechanical engineer, but he is a real motor head. Chris is an expert on rebuilding 50 year old electrical equipment like 15kv breakers. This breaker would not open, and it was stuck so you could not unplug it. Chris injected lubricant into the socket, and had the men rotate the coupling by hand so the lubricant (special lubricant that Chris had to specify and buy) would penetrate. The were then able to unplug the breaker for the first time in 30 years. Chris then had to figure out what was wrong with this complex piece of equipment that can interrupt a 25,000 amp fault in 5 milliseconds. It turned out some grommets were worn. Chris replaced the grommets with ones he had specially machined. Chris then had to tune everything up so the breaker could interrupt a 25,000 amp fault in 5 milliseconds. The only other engineers who can do this are old enough to be Chris's dad, or granddad. These are some of the things real engineers do.

Q: Electrical system in a residential building. When we use any equipment on one phase the lights on that phase dim down but and the same time the lights on the second phase become brighter.: The voltage on loaded phase dips on the account of starting current of equipment. This problem is specifically critical in case of motors. So the dimming brightening happens because of unbalance is 3 phases of the installation. This condition is completely normal keeps happening always.

Q: I just moved into a house a week ago and for the past couple of days weird things have been happening. The night before last my tv in my bedroom changed channel by itself and also I had a playstation remote sitting on top of my playstation and that fell on its own. Last night I was laying in bed and my door opened by itself and I am 100% sure that it was shut all the way. And again in the middle of the night it changed channel. I'm starting to get scared because all of this happens when my boyfriend is at work and its just me and my two boys. Is my house haunted, and what can I do?Btw my house is probably 100 years old.: First lets look at the debunking side, some electrical equipment can have the same frequency, therefore operating that other item can change the channel, unless a neighbor lives near by and he is operation his TV and through the windows your TV changes. Since you just recently moved, things will seem different, and did you put the play station flat, or because it wasn't stored correctly it fell. New home and doors may operate differently, especially since it's an old house, the door will usually swing one way, and some just takes a small amont of wind, air vent whatever. First check out all these things and see if you can ascertain if any reason why this is happening and if you squarely cannot debink it, then perhaps it is paranormal.I am a big believer in the spiritual world since I have seen so many of them, and made communications.in the fifty years of experiences one one was a bad spirit.so I don't worry when I find out a home is haunted, I have actually made friends with one because she is that nice to me. So perhaps it's a good spirit looking over you and does these things to allow you to know it's there.

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.: Get and browse their prospectus first. Then overview AT LEAST the beyond two or three years valued at of annual reviews and examine earlier 12 months projections to how they did in years to come. Are they doing what they are saying they are going to do in years to come? How good have they weathered the recession? Is leadership conservative or dicy? Are there any pending regulation fits that would have an impact on their percentage fee (up or down)? Educate your self earlier than you make investments. NEVER take a scorching tip in a public discussion board. EVER. As normally as no longer it is a pump and sell off rip-off and for those who get stuck up in it you are prone to both lose your blouse or uncover your self at the horrifying finish of an SEC research, relying upon the way you time your buys and sells.

Q: I want to open a electrical contracting business down in Brisbane or Sydney after i have done my apprenticeship and had a thew years of experience I'm 16(Australia).Possibly even higher a thew lecky and also sell stuff like inverters etc. electrical equipment.The business would service the commercial side more then the domestic side.would this be a viable business or not.and would it be possible to make any money out of this to look after my family and look after my own family. Perhaps a couple hundred thousand a yearor would it be better to just go to the mines By the way i do study business organization and management plus economics so i have a general idea of what would be required like a very detailed business plan etc.: Your okorder

Q: I will be traveling to India in the next month. I have my laptop, camera and other electrical equipments which will need to be charged. I have heard that the voltage in India is 220 V and not 110 V. All my appliances work at 110 V, how do I make it work in India?: Plugging a 110v equipment to a 220v outlet will produce a dramatic exploration of the experience of sight, sound, scent and in all danger touch while you're in close touch to the device. The journey will end with a cry and an ensuing holiday to an electronics restore middle in case you value the precious equipment you have brought about to torment. any incorrect way around isn't as dramatic as above yet will result to a difficult sensation ending with a question as to why the appliance did no longer progression. whilst found out and corrected, the appliance will thankfully serve its purpose given the main suitable voltage to paintings on. If the authentic clarification for ineptitude isn't got here across, the appliance could be further yet mistakenly dropped on an identical electronics restore middle as above with an ensuing sensation of an inherent ability resembling a cucumber that must be observed via a boisterous mark of cachinnation.

Q: I dont understand how charged particles in the sky would effect the electrical system down here.: It couldn't. Solar flares happen on the Sun. Some solar flares trigger coronal mass ejections (CMEs). If pointed in the right direction, some CMEs reach Earth. Most CMEs are deflected harmlessly by the Earth's magnetic field, causing auroras. Approximately once a century, there has been a CME powerful enough to penetrate the Erath's magnetc field on cause induction in electrical grids: telegraph lines in 1859 and Hydro-Quebec's transmission lines in 1989. Now that we are aware of the problem, warnings are issued and precautions are taken.

Q: Hey im sell a electric fencing sword wet because I just cleaned it with water because im selling it on OKorder.: Getting any electrical equipment wet with water is a bad idea. The water hastens corrosion, and if it is still wet when it is plugged in, the resulting short-circuit can damage it and other electrical equipment further. If the weapon is an epee or foil, the barrel of the tip will hold the water and rust the spring(s) and contacts. In the future, the best way to clean a weapon is to wipe off any dirt or salt with a clean, damp cloth and dry it immediately. Use a Scotch Brite pad or equivalent to gently remove any rust or scale from the blade, being careful not to damage the wires and insulation in the groove. To keep rust off the blade, wipe the blade with a light coating of machine or gun oil, a paste wax, or silicon car wax. Keep blades away from sweaty jackets, etc. Colored blades, FIE-rated blades, and maraging blades rust less than regular steel because they are either coated with an anodyne (in the case of colored blades) or are made of an alloy that is rust resistant.

Q: How can I ensure my computer is properly backed up and the back-up files are unaffected by the sun? Would putting everything on CDs and DVDs work? Which would be better; an external hard disk drive or an external optical hard drive or jusr DVDs/CDs?: The okorder

Q: How do I calculate (using mathematical equations) the load of my equipment to support and find the correct alternator and battery for my vehicle? I'm looking for an in-depth equation that explains what I have to find from the equipment specifications to the mathematical part evolved. I want to make the right choice for my vehicle without any word of some salesman to sell me a product with little to knowledge of the product they are selling.: Ideally , you want an alternators output amperage to be equal to the maximum amperage draw of all of your amplifiers plus about 40 amps to run the rest of the electrical equipment in your car. So if your amplifiers draw 150 amps at full power you would want a 190 amp or larger alternator. If you can not get a alt. that large , extra batteries can help fill the gap. The rule of thumb for batteries is one cca of battery power per watt of amplifier power.
