Q: im a freshman in high school and was wondering if i wanted to become some type of electrician in the navy what classes i should be taking, doing good in? also what is it like being in the navy and does everyone get in i really would like to become an electrician in the navy do i still have time to improve and meet my goals?
Don t issue it gained t be that undesirable. yet once you % training and education nicely thats all you will get. NO journey. What you're knowledgeable to do isn't what you will do. you will nonetheless could get a level once you get out. it is going to probley be quicker then later. All you may say once you're complete with the 4 years is that have been given your hands grimy and a few fancy identify. Oh and a cool uniform. flow get a e book at domicile depot approximately ordinary electricity.
Q: I have an item that is magnetic and it was accidentally heated. That took away a lot of the strength how can I restrengthen my magnet?
It needs to be rezapped. Either replace it with a new one of the same type, or return it to the maker for the fix. Converting a permanent magnet to an electro-magnet probably won't work very well, because magnetic material, oddly enough, does not conduct magnetism well. Electromagnets are made of soft iron or plain steel.
Q: Hi we are going on holiday to Brazil and staying at the Super Club Breezes Hotel in Costa De Sauipe where they have 220 v AC but while we are in Brazil we are planning on also visiting Rio and Iguassu Falls where we understand they have 110 v AC. What exactly will we have to buy and take with us so that we can use UK hair dryers, phone chargers and other assorted electrics. Thanks AJ
Am really sorry AJ but I don't know. When I moved to Brazil I moved from Germany where I grew up so I can't say what you will need for english equipment to work there. I think however I have come across this question before and if you search the answers you might find itagain sorry I can't help you further
Q: hi i have a black glass tv stand which makes the dust very visible, i normally wipe with a cloth, but i don't really want to do this like every time it piles up with dust, is there a thing which removes dust automatically (please give me a link either OKorder or which supports pay-pal) thank you
You could turn your Living room into a clean room, and put on a bunny suit every time you go into it!
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.

Q: i replaced my home theater system thinking it was busted but when i recieved my new one it still had the same buzzing sound i noticed the buzz is in the bedroom too
No, it really wont help. I'm not really sure what would help this, or what is causing it. If i had to take a guess, it's gotta be the quality of the wires touching each other likely coming out of a small hole in the back of the entertainment center. Honestly, it could be a number of things, and without looking at it, i have no idea. But a surge wouldn't help. a surge is designed to do one thing, detect power surges and shut down before they happen. It's basically exactly like the surge protector box, except designed to detect a smaller surge, and react quicker, to protect valuable electronics. For things like interference, even if the interference is caused by electrical charges in the power supply (which is unlikely in itself), a surge protector would not be able to detect the interference at all because it isnt sensitive enough, or else it would be able to detect it (also not likely) and would simply flip off every time you turned it on because the interference would simply trigger it. over and over again. For this problem you need to attack the interference at the source. where that is, i couldn't tell you.
Q: I accidentally connected the negative and positive terminals of my battery with a wrench, I have checked all the fuses and none look to be blown. What else should I be looking for?
Your looking for a melted fuseable link-- noy a fuse. It will look like a burned wire
Q: 20 ft. off the ground,miles of steel rail supporting it, thousand's of gallons of diesel, electrical equipment all around.
Safe. You are surrounded by metal which forms a pretty good Faraday cage. The loco is well grounded via the rails. Apart from the bang of thunder you might not even notice the lightning. The Diesel fuel is in a steel container under the loco and even better shielded than you are.
Q: If I decide to choose electrical engineering as my college major what would I be doing on a regular basis for my job?
Shelly answered pretty well but there's sooooo many fields you can go into, ESPECIALLY if you get an education in Mechanical Engineering too. I'm going into Electrical Engineering at ECE Illinois, possibly the best school ever created. My (dream) career is working at the Department of Defense for the advancement of science and technology, hopefully more based towards making everyday life easier, alternative energy, and warfare. There are A LOT of careers you can get out of it, like shelly showed, but more. yeah, you just got excited didn't you?
Q: i dont understand this, every surge protector claims to protect phone lines from surges but why?
Because DLS and phone lines operate on voltages and currents and are susceptible to lags/spikes. GL
