- Q: I know you need fuses for cars, electrical equipments, etc. I don't get what they are really used for?
- a fuse is the last defense for an electrical device. given that electricity needs a complete path to flow in order for the circuit to be active a fuse acts as a switch to an extent. that same fuse is amp sensitive. if the circuit draws more than the fuse allows the fuse will over heat and open the circuit. typically a fuse is set up to be about 20 % more than the circuits typical amp draw.
- Q: 1. what is electrical and wiring system?2. what are the factors to be considered in designing an electrical wiring system in buildings?3. what are the possible ways of saving energy when designing an electrical and wiring system in buildings?i just need the experts opinion about this.thanks!
- A building electrical system includes all of the equipment and wiring designed by the electrical engineer. This begins at the utility power connection and includes the service entrance equipment (meter base, current transformer cabinet and main disconnect switch), a main distribution panel (main breaker panel or main switchboard), and branch circuit distribution panels. The electrical system includes all wiring from the connection to utility power to connections to all electrical utilization of equipment. The electrical system also includes building lighting and lighting controls, building premise wiring for computers, computer hub room equipment, security systems, public address/broadcast system, keyless entry system, fire alarm system, and standby and emergency power systems. The main factors to consider is square footage of building, type of occupancy, number of occupants, and applicable local codes, the number of floors in the building, location of exits and stairwells. These considerations are used especially in determining what voltage with which to serve the building and size (ampacity) of service entrance and main distribution panel. These statistics are also important in the design of the fire alarm system. The main ways to save energy is through use of occupancy sensors and daylighting controls for lighting (the latter assumes windows or skylights for introducing daylight). These controls will keep the lights off unless specific areas are occupied, and lighting along with HVAC are the largest electrical loads. Energy costs (both electricity and heating fuel) can often be significantly reduced by incorporating CO2 sensors and variable frequency drives to control air handlers (large fans) rather then running them continuously at a rate to support maximum building occupancy, as is the case in many buildings.
- Q: I'm considering buying an assortment of electrical equipment whilst on holiday in the US. Will they work in UK? Thanks in advance1) TV. Gut feeling is that the digi tuner (NTSC/PAL) will be different and its going to be a nightmare with the actual power.2) Nintendo DS. I think i will be ok on this one as games are not region enabled. Charger maybe an interesting one.3) Cable modem. No idea :) but i need a cable modem for home.4) is there such a thing as a DAB radio in the US? I saw some really strange radio setups but no DAB.5) Digital Video Camera. Makes to avoid for the change to UK?Thanks again for reading and taking time to reply.
- Isn't it great us brits being so much richer than the americans two dollars to a pound the poor things. You're doing a really good thing buying from them it's like buying charity christmas cards gives you feeling of helping those less fortunate.
- Q: I was wondering, if everyone on earth was to disappear and there was no one to work the electrical grid, how long would it take for 1] The electrical power lines themselves to decay?2] The electrical substations to break down?3] The transformer units to break down?4] Any other electrical equipment to break [such as those boxes on the power lines, as well as ANY other piece of equipment on the electric grid]?P.S- Don't give how long it would take for the power stations to stop running, I already know that. Just answer the four questions I asked.
- Electrical substations may break down. 2]. Substations require regular maintenance.
- Q: Any tips for a rock band that will be playing shows in the next month or so? Set-up, breakdown of equipment, working the crowd, preperation, etc?
- Learn to put up and break down your equipment quickly. I've seen a drummer take 30 minutes to set up the most basic of drum sets when the set was brought in. Have backups for your guitars and electrical equipment. A broken string on a guitar is a 15 minute pause on your set (experienced that from the same band that took that long on the drum set) to fix it. Ignore the crowd if you think they are bored (in music videos those crowds are paid to be all festive, but they are no where near that in real life). If they aren't paying attention to you, you can forget the onstage talk and sing alongs. Ignore the drunks (talk with the manager before hand on having the manager remove the noisy drunks). Have your merchandise (same band above forgot their stuff and I wanted a CD)!
- Q: I am about to finish my BS in Electrical Engineering and was considering getting a MS in EE but considering how the economoy is and the fact that the Bureau of Labor Statistics say it should grow slower than average. This being said what do you guys think is the most prudent thing to do in my case. Go for an MS Engineering Degree or start out with another degree maybe in healthcare.
- I agree with Bimmer, if you decide to stay in school, go for the MS in EE But MS can be quite different from BS. more pure math. and mainly RD, papers , thesis if you like sort of work go for it. Otherwise, go find a job There is a lot of job that are not advertisedespecially in EE.
- Q: i am attending college in the fall, actually school starts on the 21st, and my major will be in electrical engineering, i was just fishing around and wondered if anyone could give me, in a nutshell, the basics of this field. since i have already chosen this as my major I do know a little, enough to choose it as my major. i just wanted to know what I might not already know. Give the names of specific jobs that would be of interest after graduation also, if you know any. Thanks!
- Galactic man already gave it all but I just wanted to wish you good luck in your studies. I just became a junior and I'm majoring in EE as well. I wouldn't suggest keeping a certain EE job in mind since you're just starting out. You really won't find what you like until you actually start taking the classes and doing some co-op/internships (if your school has a program like that).
- Q: i am very interested in pursuing a degree in any type of engineer that designs military equipment it can be communication equipment, guns, tanks, grenades, any type of equipment im just wondering what engineer or designer does that type of stuff
- Well depend on the equipment. A mechanical equiment, by a mechanical engineer An electrical equipment, by an electrical engineer A transportation equipment, by mechanical, automotive, civil, topography, etc. engineer. Some weapons, chemical engineer, aerospacial engineer, civil engineer, topography and physics. Softwarewellsoftware engineer and stuff. The basecivil and structural engineer of course
- Q: capacitor failure inductor failure thyrisitor failure i wonder if there is any solutions for these problems !!thank you in advance .
- Check the voltage and temperature ratings on the cap. Use a higher voltage and higher temperature unit if needed. Voltage rating should be 50% higher than system voltage for best reliability. Look into using alternative designs that eliminate the cap. Inductor, check current and current rating, also temperature. Thyristor, power rating is all important, but voltage and other specs are also important. Check that all of these have sufficient margin. Mechanics are also important, eg, a firm attachment to the heat sink, one that vibration will not change.
- Q: anyone knows some practical situation when a resistance maybe used to model part of a circuit, a component or electrical equipment
