FAQ

Do electronic engineers make audio equipment like headphones, amps, and speakers? And do you learn this in engineering schools in college?

Yes and No. Although all electronic engineers should have the basic knowledge, you can nowadays find that hardware engineers tend to specialise in either digital or analog electronics. A typical digital hardware engineer may struggle, while an analog engineer certainly can design audio equipment. I doubt that electrical engineers could do the job, they are specialised in power distribution.

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.

How long did it take you to complete? What job do you have now? I am interested in going to school for that and wondering what type of jobs I might have.

It took me 4 years to complete I am in a leadership development programing at a large aerospace company A lot of my classmates got jobs in the defense industry. Most are working in computer enigneering, rf design, or software

I have a full-time job but would like to dabble in residential electrical work for friends and family. What would I need to do? I would like some kind of formal license and training but don't want to go back to school or commit to any long-term programs. This is in Massachusetts.

Massachusetts Department of Public Safety requires that only licensed electricians can work for hire on electrical equipment, wiring, conduits, motors, etc. To get a license you will be required to work 4000 hours under a licensed Class A or C electrician and complete an extensive training course. Also, you will be required to take and pass an exam. After all that you are required to take 25 hours of certified training every two years. This will be or already has been increased. To work on CCTV, Burglar alarm systems, or Access Control systems a S license is required. If you don't get paid you still have to worry about the exposure and getting insurance to cover this exposure would be impossible if not licensed.

Hi all, i wish to travel to the states soon and would like to bring some electrical items back, as-well as clothes when i travel to New York. From research i have already learned that these goods brought back into the UK can total ?340. But my question is this, if i travel to the US with very little luggage - no clothes or electrical equipment. Then in New York i buy a nice laptop, ipod touch, digital camera (but take the electrical stuff in with my hand luggage) how will they be able to know if the items i want to bring on the plane were in fact brought with me from the UK to US and were already mine?Also if customs say that i have to pay tax for going over the ?340 - how much will it be? say e.g. on a $2000 laptop?

They might have a suspicion that you are importing items back to the UK (rather than having taken them there in the first place) when looking at the US-style electrical plugs. Given that these are not the same kind of plug as is used in the UK, you might raise suspicion when everything you bring back has US plugs (instead of UK plugs with a US adapter). I'd also note that failure to declare goods purchased abroad may make you liable for fines levied by HM Revenue Customs, as well as Customs seizing the goods. For purchases above the ?340 duty-free limit, the taxes paid depend on the total value. The second link below states that the duty paid on goods in excess of ?553 depends on the type of goods imported, and that you should contact HM Revenue Customs directly to find out what duty would be imposed.

I have worked there as an electrical engineer but in design for a consultant. I would like to know what are the major things to account for (DB's, wires and cables, ducts, conduits.) and how to estimate them for a typical 6000sq.ft 2 floor villa

If you have the design drawings, you simply have to make a material take-off list. The main drawings are: General Layout Grounding Layout Electrical Equipment Layout / Schematic Riser Diagram (Fire Alarm) Lighting Layout At the very least, you need to have the General Layout drawings (to know how many rooms you've got) and you need to know the electrical levels since some houses might require 380/480 3-phase for elevators and large electrical equipment. Working room by room, you will estimate cable and conduit lengths, the number and specifications of the DBs, number of lights, outlets, switches, buzzers, intercoms, smoke detectors.

Actually in position, we have provided shade for an electrical equipment but sun is hitting during morning and evening. Can it be called as a shaded area?

Outside ambient temperatures are always measured in the shade away from direct sunlight. If your equipment is seeing direct sunlight in normally convective air, then you should use an infared remote sensing thermometer to measure different points on the outside and the inside of the equipment (if possible) to determine the ambient temperature (when exposed to direct sunlight). Alternately, you could place a thermistor, thermocouple, RTD, or semiconductor temperature sensor inside the equipment (always in the shade) and run wire leads outside the equipment container, then measure ambient temperature inside the equipment with a meter on the outside. .

If humidity of a spacecraft is too high, how can it affect a crew and its equipment? what if it was too low?my sister did not get to go on her field trip but they gave her the worksheet this is the only question she cant answer please help!

mold can make people very sick or die. also moisture could iodize electrical equipment.
