Q:If a landlord is renting out an old home and the tenant suffers regular damage to his or her electrical equipment, would the landlord be responsible for having the building wiring updated so that such damage does not continue to occur on a regular basis? What if the cost of such repairs far exceeds the rent that the tenant would be paying? Would the tenant be legally able to break a lease without paying fines in this type of situation?
As long as the wiring was at code when the house was built he does not have to change it. BTW, it would cost about a years rent, you are talking about a major renovation. It is normally only done during other major renovations, not by itself. This does not break your lease. Haven't you ever heard of surge suppressors? Buy yourself some.
Q:I have heard, (I can't recall where), that the Earth's natural magnetic field is slowly declining. I have also heard that solar flares can disrupt the operation of electrical/electronic equipment. Would either of these natural phenomena affect the operation of electronic/electrical equipment? Please answer each query briefly, and provide links if possible.
The magnetic field of the Earth is only an issue with things that measure or otherwise require the presence of the field, specifically compasses, only at that, only magnetic compasses. Most modern navigational equipment use gyrocompasses, which measure the rotation axis of the Earth and therefore, do not care whether a magnetic field exists. If the magnetic field were to disappear tomorrow, only magnetic compasses and certain geologists would be affected.
Q:Hey Guys !I just finished High school and I'm quite certain that Engineering is my first choice, however, I'm still a little bit hesitant. I'm choosing between electrical or mechanical! I think I like both majors and as far as I know Mechanical is the science of moving objects where you can get more hands-on experience , while electrical engineering is more imaginative. You can't really see electricity , thus it's more challenging ! To be honest , I like challenges but I don't want to end up regretting any decisions! Can anyone give me any insights , advices or opinions on both of majors ! What I'm going to study , what can I do , anything that could practically help me decide ! Thanks in advance
I believe you grasp the essential intellectual difference between the two fields. In the study of both disciplines there are laboratories where you build things. In electrical labs you build circuits, and in mechanical labs you use lathes, drill presses and milling machines to build mechanical devices. When you are out of school and working, you will most likely not be doing anything hands on except inspecting equipment, systems and facilities. Your principal work will be analyzing, documenting, reporting and creating design/construction documents. I had an orientation to both fields (mechanical and electrical) as from the time I was about 13 I rebuilt engines in a machine shop and loved to build all sorts of mechanical things on a farm. But I also liked to design and build receivers, transmitters, amplifiers, etc. Ulitmately, I was attracted more to electrical engineering because it seemed more esoteric and mysterious; but I think I would have been happy and successful in both fields, and possibly even in structural engineering. These fields apply math and the other sciences, and require creativity to find ideal solutions. Civil engineering seemed too mundane to me.
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:Fires are classified by the fuel involved. Name the type of fire extinguisher which must be used in the event of the each of the following fires 1. Cooking oils 2. Flammable liquids 3. Electrical equipment Thanks.
For cooking oils, greases and paints or Flammable liquidstype B while electrical equipment its type C fire extinguisher.
Q:And what does electrical engineer teach in college? Is it good for girls?
Sometimes electrical engineering does involve computer science, but it depends on the school and the area of concentration. Electrical Engineers often do PLC programming for robotics and equipment. Both electrical engineers and computer engineers may work on developing circuit boards or computers. I know a few girls that studied electrical engineering. One of them got a job as a systems engineer for the SI organization, a large company owned by Lockheed Martin. Engineering is a growing field for women. With gender equality slowly getting better, more girls are gaining confidence in going for manly majors. There is almost no hands on work in engineering. You are not expected to know how to fix things. An engineer is a problem solver. The responsibilities of all engineers are the same regardless of job position or major. Their responsibilities are to invent, create, design, develop, improve, maintain, control, and sustain the following: -Products -Processes -Systems
Q:all electrical equipment goes dead in car. If disconnect battery, then again appears to have electrical power, no fuses in panel or battery relay blown, but ignition clicks once and all electrical out again in car and starter does not engage.
Sounds like the ground cable is loose.
Q:I want to know if it would be feasible to make exercise equipment (like a bike, treatmill, stair stepper, etc.) that would produce a small amount of electricity when used. Could this type of equipment be modified to produce enough electrical energy to make a noticeable difference in a monthly power bill? If it was feasible, think about the benefits! Not only would we have a new (albeit small) source of energy, but we might be motivated to get off our butts and exercise more. Okay, its a wacky thought, but I just wondered. What do you think?
The most effective way of getting green is to cut the needed electricity/gas income to work. How to do it? Many electrical and gas systems are the 20th century version of a mechanical device powered by water, wind, gravity and/or animals. Very simple principles applied to complex machines makes something both astonishing and effective. You could pump water out of a river just by using its own torque. Imagination is 99%, as Einstein said; be imaginative and create something that is both efficient and useful for you. And if you can do it for others, go on. After all, Rome had the most efficient water system for a long run; until New York in the 30s, no other city brought more water per day than Ancient Rome at its pike. Only used gravity New York used pumps, many of them. The Islam medieval world used, created or modified many things which are still in use today. The mechanical world is not a modern invention; the man just remembered how it used to be.
Q:electrical safety product
A lightning rod, sometimes called a lightning arrester is something you mount on top of your house. It is a pointed long metal rod (or several of them) that is mounted on the roof so that it is the highest object. It is connected via a heavy metal cable to a ground rod which is driven into the ground nearby. It will attract any lightning bolt and dissipate it to ground. You may be talking about a surge protector, an electronic device usually mounted in outlet strips, that provides protection to voltage surges and spikes, which can be caused by a nearby lightning strike, or by inductive loads switching off. Surge protectors are usually varistors, which are power devices that have an V-I characteristic that causes them to shunt voltage much above the normal line voltage to ground.
Q:I am 57 years old. MBA graduate with substantial experience in Electrical equipment maintenance. I have also experience in NDT.
My guess is that your age is a stigma, though nobody will admit to you that they won't hire you because of your age. They might not even be conscious that they are discounting you because of your age. Look around the office when you go for your interview. Is it filled with younger, or with older people? Do the regular stuff too: Go on the internet and research good interview skills. Practice with your friends. Ask your friends to critique your resume. Look up the company on the internet and come up with some specifics about why you want to work for that particular company. Yeah, that's a good point Your salary expectations might be significantly higher than someone half your age. Better check into that. Also, I have no idea what NBT is. You might edit your question so that people have a better idea of what your experience is. Good luck!
