- Q: 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.
- Q: Im doing a report and I've looked jzt about everywhere and i cant find the answer to this question, please help
- Population below poverty line: 21 % (2002)
- 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?
- There are some things that Radio Shack is good for. Converters for foreign travel is one of them. You'll need an adapter for the different plug configuration AND you'll need a voltage converter. Both are also available as a package. And a lot cheaper, cleaner, and more reliable than trying to build your own.
- Q: Can we use land line phone to control houshold electrical equipments. Is the techonology available. I am asking in sense how we use IVR when we call a bank, can we have someting in similar lines. For example, switing on a microwave at home before i leave office.
- The answer is a qualified yes. You can connect your lights and appliances to X10-based switches and dimmers, and use the X10 Telephone Responder to control them remotely by phone. This will not allow you to turn on a microwave, because microwaves require their buttons to be pushed. But you could control lights, appliances and HVAC remotely with the right X10 receivers connected. See the links below for some phone-based controllers.
- Q: I dont understand how charged particles in the sky would effect the electrical system down here.
- It wouldn't DESTROY the grid, it would trip the circuit. Imagine adding an incredible charge into any circuit what happens to the current? The resistence? The most notable example of this is the event in Quebec in March of 1989.
- 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: exactly 5 min later:a- Would it damage the power grid?b-Would sudden surge after 5 min create even a bigger loss in energy than what was saved in that 5 min period??I am not an electrical engineer? I keep hearing that sometimes turning off an energy source for short term does not really save any energy? Is that true?Thanks alot.Could you help me with these 2 points?
- Yes, in this extreme case, it may damage (BOE calculation: 2 million x ~500 watts: ~1 billion watt) if they are on single grid. In many of equipment (motorized) start-up losses are significant. So, you may end-up with little saving and a big grid failure. But if you leave aside such extreme situations, it is always good to turn off electrical equipments even for a short gap. And just to add, beware of leaking currents (e.g. not disconnecting appliances from the power plug) which are bigger concern.
- Q: for a store of electrical equipments, I want to create a database for it, what is the data that I should maintain in this database (the names of the columns)?
- You need multiple tables. Using int() auto_increment primary keys for linking each section of data you want something like : stock_codes ( id int(6) primary key auto_increment, stock_code varchar(45) unique key, stock_description varchar(45), stock_qty int(6), suppler_id int(6) ) stock_movement ( id int(6) primary key auto_increment, in_date date, out_date date, moved_qty int(6), stock_id int(6), ) It helps to have tables of suppliers details, client details, sales person details, department details etc. If items have possible alternative suppliers you dump the supplier_id from the stock codes and use a link table for the stock id and supplier id to identify each inward transaction. Add tables for any additional information using links from the other tables to co-ordinate the data.
- Q: I'm a physics students and often come up with seemingly stupid questions I can't really find an answer to. If the human body acts as a resistor of around 100 kilo-ohms or more, how is it that I could die by grounding myself with the hot terminal of an electrical outlet?I understand that the average current flowing through me is the product of RMS-voltage over resistancebut this value doesn't seem NEARLY high enough to do any damage much less for me to detect.Thanks!
- Mr. C. has an excellent answer. I might also add that as an electrical worker I find it very important to make sure that when I work with electrical circuits and safety equipment that I try and eliminate a flow path from live to ground that can pass through my heart area. We always use safety equipment and follow procedure but at times you have no choice but to get very close to energized exposed circuits. They can and do bite. I have been known to take an extra step and insulate exposed energized areas that are near my legs when I am working with energized circuits above my waist.
