Q:Is it okay to use ATEX certified electrical equipment on Shabbos?
When I was in fourth grade, the science teacher taught us the physics definition of work and explained how it differs from the everyday definition of work Much like that -- Jewish legal definitions of Hebrew words do not always line up perfectly with the everyday use of English words that aproximate them. With electrical items, the prohibition of fire is only one of the prohibitions to be aware of for Shabbat -- off the top of my head, there is also boneh (building) and bishul (cooking) On the reverse side -- your logic does not hold in even the most basic English definition. It is only the Karaites that believe there is a Shabbat prohibition of fire, the normative prohibition is on making fire and putting out fire -- thus, there are quite a few devices used on Shabbat that are straight forwardly on fire (well, heck -- just think of the candles themselves!!!) A Shabbat lamp is simply always on - but has some cover to keep the light from bothering. Hopefuly, this whole structure is well insulated (I don't know -- never used one)
Q:Electrical Engineering anyone?
Sky is the limit! Beside all the obvious electrical engineering jobs such as circuit designer (both digital or analog), system engineer, semiconductor process or equipment engineer, power engineer, communication engineer, product engineer, device engineer, QC engineer, field service engineer, etc. You can be an astronaut, mission control engineer (for NASA), technical marketing or sales engineer (with MBA), apply for medical school, and God forbids be a professor in engineering (with PhD), Simply too many to list.
Q:Can you connect an electrical equipment requiring 220-240V to an outlet producing 110V?
No but it makes me have a good cry every once in a while. Lately i've been getting really stressed out about our family finances. I feel like a loser because we can't seem to keep our heads above water. It seems that our bills are rising by the day. Between paying for higher gas and food prices, we're really stretched. Financially and spiritually speaking, I wanna scream every time I get a bill.
Q:Is it possible that electrical surge caused by lightning fry one small chip of my security alarm nothing else?
The alarm company employs the expert who says so! I'd say it is completely possible. One problem with an alarm system is all the wiring connecting it to the various triggering devices. It is usually long, and elevated, not shielded in any way. It works like a large antenna. So, a lightning flash doesn't even have to cause a surge on the power lines, in order to induce a voltage on all this wire. Distant lightning will produce an EMP (electro-magnetic pulse). It is like a strong radio signal. It only has to exceed the breakdown voltage of any chip it can get to. As this has to be some particular chip, it could be taken out alone. It only takes the destruction of a single gate in it to render it useless. I'm sure the manufacturer would have had enough experience to realise the cause of that particular chip being taken out! Nothing else in your house can present such a large antenna to the pulse.
Q:what is principle of lightning arresters?
A lightning arrester is to protect equipment from getting damaged from a lightening charge. Electricity will go to the nearest ground and the best ground or negative side - which is the ground you are standing on. The positive side + is in the sky, the higher you go the higher the charge ( in the millions of volts ). Air is the best insulator for high voltage so you don't get electrocuted when standing under a high voltage power line, or in a airplane. The + and the - are trying to equalize so the negative side runs along the ground looking for the positive electrons, and the positive electrons are looking for the negative, like a magnet so when they get close enough, the negative charge (amps) goes up to the positive charge burning the air and making a path so the positive charge can get to the earth. If you ever watch lighting-stroke you will see a light flash go up before the positive charge comes to the earth. Lightning arresters protect your computer, TV, and all the electrical equipment you have. When hair stands up on the back of your neck, get out of there.
Q:Electrical system in a residential building.?
Someone has split the two phase into two one-phase circuits. Putting a load on one side lowers the voltage potential, which raises it on the other side. This is completely normal.
Q:What kind of equipment would you need to convert cosmic radiation into usable electrical energy?
What kind of equipment would you need to convert cosmic radiation into usable electrical energy? Cosmic radiation is basically just bare protons. It is scattered over the entire atmosphere, and nets to lightning when solar wind contributions are factored in. How can you harness lightning for driving electrical loads? Considering Earth is being bombarded by cosmic radiation 24/7, is there a way to harness this energy from outer space and power homes with it? Not enough power, and too large an area. What kind of devices or equipment would make this possible? Lightning rods and big capacitors.
Q:school video help on electrical safety?
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:Hi all , I'm creating an Inventory system .?
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.
