Q: A question for electriciansi am getting a bachelors degree in entertainment technology. The apprenticeship program is closed but i would like to get a head start for the next go around. Should i go to school and get a masters in electrical engineering or should i become a grunt and get the experience? orwhat do you guys think? I know local 3 is hard to get intovery hard???
If I have been hiring an electrician, i'd sidestep every person with a posh enterprise call, and that i'd probable leaf by using telephone e book in alphabetical order, so i'd propose something like Abbey electric powered centers (except you're blessed with a time-honored or surname that comes early interior the alphabet).
Q: I know you need fuses for cars, electrical equipments, etc. I don't get what they are really used for?
A fuse is a circuit breaker. It is placed in the line of an electrical circuit to protect against power surges that could potentially damage the electrical component. If a power surge happens, the fuse will blow, cutting off the flow of current and protecting the component. Without the fuse in the line any spike or surge of current in the circuit could be sent into the electrical component and cause serious damage.
Q: 1.What is Rated AC voltage? Why we would like to state Rated instead of Nominal?2.What is Nominal AC voltage?3.Explain rms value for AC voltage. What is it's relation to Rated/Nominal Voltage?
Rated Voltage
Q: considering that he is specialised in power engineering or does he administers them.
Electrical engineers would be primarily interested in the driven equipment namely the generators. They might be involved to a slight degree in the design of engines and turbines but not to the extent that a mechanical engineer would.
Q: I want to use scientific equipment that will measure the electrical conductivity of water. I only want to electrocute the water and measure the current as a last resort.

Q: I am looking into putting a trailer hitch on my truck so that we can move. But I get a little bit confused when the mechanic starts talking about electrical equipment. Do I want a round 7 or a flat 4 or both? And is it necessary to also install a trailer brake controller?
The purpose of a truck is to do whatever you ask of it. For a lightweight trailer all you need to connect are the trailer lights, a flat four connector. For bigger trailers you need trailer brakes, a brake controller, and a round seven connector. You can get a plug-in adapter to go from your round-7 to a flat-4 if you haul a light trailer. You cannot go from a flat-4 to a round-7 with brakes without re-wiring the truck. Do it right, do it once.
Q: I need this for my class and I just need a site to start off with! Thanks
(1) Try: MSDS (wikipedia) (2) Also try: Electrical equipment in hazardous areas (wikipedia) It may depend on which country you live in. References and external links for (1) and (2) above are included.
Q: for school we have to do a video on electrical safety and what to do and what not to do in a office (at work) and please give me some ideas to have that arent not to touch a live wire because i already have that idea! thank u and please help me out
1. Don't overload receptacles with too many plugs. 2. Don't cut up extension cords to make them work on equipment they shouldn't. (for example - Don't cut a standard extension cord plug end off, and splice it with a printer power cord, if the plug end of the printer is still good, but the wire is bad. - The cable you splice may not be rated high enough to handle the amperage of the printer) 3. Make sure electrical items aren't in areas they can get wet - A leaky roof, dripping onto a light fixture. 4. Don't run power cords across the path of forklifts, or other vehicles unless they are rated to be able to withstand that kind of traffic. 5. Make sure a qualified electrician does electrical installations - Things can get wired incorrectly and short out, spark, or catch fire if wired wrong. 6. Always use wire nuts, and/or electrical (rubber) tape when applicable when connecting wires together - this prevents loose connections, and prevents arcing or sparks from the live wires touching metal objects or each other. 7. When digging in the ground more than 12 deep, make sure you call the electric and gas companies first - Usually electrical and gas lines (water lines sometimes too) are about 18 below the surface. If you cut or break these, you can potentially be killed if you come in contact with the electrical lines, because the voltage outside of your home or building is considerably higher than the voltage wired indoors. Hope these help!
Q: If you have a cell phone near any sort of electrical equipment that emits noise, old or new, you'll hear that skipping buzz noise. What causes this exactly, what is it, etc?
The cell phone in fundamentally a radio. Radios emit radio frequencies energy which will interfere (RFI) with other audio equipment like an AM radio. You hear the noise while the phone is communication with the tower. It does this from time to time to let the tower know it is online and ready to receive data and of course to transmit/receive data. Hope that helps.
Q: i want to where I can transformator ( i do not know the name)But I whant to there is some equipment the you connetectwith your device it will change the current. And please wherecan I buy and approximatly what is the price?Thank you
yes u can but u would need a power volt changer to make them work in the usa the power converters cost between 10.00 - 100.00 dollars
