- Q: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.
- I am currently studying to be an electrical engineer. It takes on average 5 years to get a Bachelor's degree. However some schools offer yu the chance to also obtain your masters in 5 years (requires alot of extra work). Electrical engineers have a wide gambit of job options. Often they involve jobs with heavy analytical problem solving, you also will be very fluent in mathematics as you will probably be required to maintain an astute understanding of calculus and physics. My father was is/was and electrical engineer who fixed medical equipment at hospitals, a field engineer. You may also be hired for you ability to solve problems rather than technical skills. It all depends what ou want to do though. My major electrical engineering with a robotics focus, so there are alot of jobs for electrical engineers.
- Q:For the past week, IT has been making the worst of coffee. This morning, I told IT that: If you don't make a good Espresso today, after 5 years, I will replace you!I don't know what happened, but IT, made a wonderful Espresso, even if the little foam on top !! Good morning !!
- LOL ! Good morning Clo ! I think I told you I bought a new one two weeks ago. IT even tells me in the morning: Good morning Jessica, you look stunning today!
- Q:I am a commercial real estate appraiser and I oftentimes need to be specific about the electrical service available within a building. I can read the service panel(s) and total the various amps volts, but I don't know what is relevant to report. For example, I recently inspected a very large industrial building and all of the service panels combined had a total of 30,000 amp, and I also noted that it had a 3-phase unit. Is that relevant to report that is was 30,000 amp, 3-phase service? Should I also report the voltage? Should it read: 30,000 amp/### volt 3-phase service. In the future, can I just read the service panel(s) and total the numbers? Just because a panel says 4000 amps, does that mean it actually has 4000, or that it can handle that many amps?I know that's allot of questions, but any help that I can get would be helpful. Thanks!
- I believe that the sum of the individual service panels can exceed the service capacity of the building just as the sum of the individual circuit breakers in a panel can exceed the capacity of the panel. It is allowable to assume that not every load will be using power at the same time. Near the meter, there should be a master circuit breaker or set of fuses that determine the ampere rating of the service to the building. In a large industrial facility, that location may accessible only to qualified personnel, and you may need to ask a qualified person to give you a description. You should state the voltage, number of phases and current or KVA available at the meter location. For a large facility, you may want to itemize the ratings of panels serving major spaces and/or verify that all major spaces have the same voltage and number of phases available. For large industrial facilities, you should also determine if the utility or the customer owns major outdoor electrical equipment that is on the property.
- Q:I have a mini (just like 5x6 inch) Lasko personal space heater. It is not originally intended for heating for tanks and cages, but since it is ceramic I was 't sure if it would be okay. It has safety features such as overheat protection and cool touch housing. Would it be good to use in the tank for the snake? He's a baby cornsnake, and the tank is a 29 gallon glass tank (like an aquarium). I already have a heating pad and two heat lamps, but it still won't get warm enough. And I don't want to use central heating to heat the whole house just for his small space. Not to mention, it just stopped working. I know I can get a conventional ceramic heat emitter, but since this is what I have, I'm hoping it will work.
- Rule of thumb with reptiles: Never put any heat source inside of the cage. Sounds like the house is fairly cool. What are the wattages you are using for the two lamps and also what are the current temps (day/night)? Please add this detail. I do have a suggestion as to part of the problem. The average 29 gallon tanks are talls, not longs or wides. When tanks are talls, they are harder to heat and maintain that heat.
- 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:If I decide to choose electrical engineering as my college major what would I be doing on a regular basis for my job?
- Electrical engineering is generally deals with the study of electricity, electronics, and electromagnetism.Electrical engineers work in a very wide range of industries and the skills required are likewise variable. These range from basic circuit theory to the management skills required of project manager. The tools and equipment that an individual engineer may need are similarly variable, ranging from a simple voltmeter to a top end analyzer to sophisticated design and manufacturing software.
- Q:If the poles switch will al of our electrical equipment still work? Or will it run in revers. Will migratory animals go the wrong way?
- The present THEORY of pole reversal is wrong. The magnetic poles of our planet are due to the spin of our planet. In order for the poles to be reversed, the spin of our planet would have to be reversed. The energy forming earth's magnetic fields is due to the energy of rotation increasing as one moves from either pole toward the plane of our planet's equator. These forces move opposite each other (called the Coriolis Effect) and meet at the equator. It is this force that causes winds and water to rotate in opposite directions. When these opposing forces meet at the plane of earth's equator, they are moving in opposite directions. These forces moving against each other through the plasma area of our planet generate a strong electric field. When an electric field is generated, a magnetic field always forms at right angles to the electric one. It is for this reason we have opposing negative and positive poles within our planet that exhibit magnetic forces in an exactly opposite manner.
- Q:I seem to have an adverse affect on computers and electrical equipment. My sheer presence seems to upset them.I'm not a stranger to technology, so it's not me being dim, but more and more often I've crashed supermarket checkouts, I was even sent to the other side of a store by my husband because the computer our details were being loaded on crashed time after time. I walked away and all was well in the world (well the store anyway). My laptop (even with the latest updates) has a mind of it's own sometimes. Coincidence or am I electrically overcharged?

All kneel before you, and your mysterious Quasi-Quantum Quark Conundrum.
- Q:Downstairs 4 outlets and 4 of the lights stopped working. One of the outlets that doesn't work has the top plugin socket working but the bottom one doesn't. Also 2 lights still work even though they are in rooms where the sockets don't work. At the time we did have two computers running from the outlets and maybe some other electrical stuff. When the electrical went out we heard electrical sparking sounds.Then like a couple months later it happened again but upstairs. The lights and outlets stopped working in 2 bedrooms and the bathroom. I don't think we had very much electrical equipment plugged in just maybe a hair straightener.If I reset the breaker the switch will move to where its supposed to be but nothing happens.How much money should I have on hand for the electrician approximately? $200? $1000?
- The key piece of information was the sparking sound. What you've got is a VERY common problem. A bad (loose) connection some where. Most likely at one of the receptacles. Since you've had the problem in more than one room, more than one circuit it's a good idea to have an Electrician come in and deal with it. Code allows us to attach the in coming wires to one set of screws on a receptacle and attach the out going wires to the other set of screws. Or worse yet, to push the wires into little holes in the back of the outlet, often referred to as back stabbing. That means that power is dependent on the connections on the recep. to pass from box to box. If any one of those 4 connection points fails everything down stream looses power. The cure is to splice all incoming and outgoing wires, add apig tail (short piece of wire) to the splice and attach it to the outlet. Much better connection and now the recep. is attached TO the circuit as opposed to being part OF the circuit. A really good electrician can make this change in a few minutes. Not counting moving furniture or dealing with other problems they might encounter. I strongly recommend having them make this change to all outlets in the house. Count up the # of outlets and multiply by 10 minutes each. THIS IS JUST a ballpark figure! I'm not there and can't say for sure! Could very well take longer but not a lot. Personally I can make the change and replace the receptacle in as little as 5 minutes, but I've run into situations that took MUCH longer. But now you have a MINIMUM time to work from. If the house is old or if the outlets have been painted over, this would be the time to change them. Available colors now include almond and light almond which in my opinion look much better than the common ivory. Hope I've been of assistance.
- Q:I sold a small bit of electrical equipment to a guy in Norway - I'm in the UK.Item became faulty after a month - I said I would refund him but I had spent the cash already and couldn't repay him back in one go. Item was returned.He agreed that I could pay it up ?899 over 4 years as I'm just a student and not working full time. It was sent in his currency and ?899Trouble is he is now claiming I've not just to pay ?899 back but the amount is to be much more in GBP's as the pound as got weaker against his currency although he stated he wouldn't add any interest on. Any advice?
- Question to you? Was any of this on paper or contracted in any way so that he has a legal advantage over you? And if not then in my opinion word of mouth is as good as it gets! And why should you have to reimburse any more than what was originally paid, not your fault the exchange in GBP's is weaker against his currency.
