Q:Can someone tell me more about this MOS or others that relate to this field of work. Also, how will a soldier be utilized under this MOS. thank you

Usmc Mos 1142

Q:I am wondering what happens when you have accidentally connected the negative cables to positive and the positive cables to negative. I have boat that has to two marine batteries and i am wondering if you were to do this will it screw things up and break things?

YESespecially if you have anything greater than a brief contact. Car and marine batteries are designed to deliver a huge amperage (that is why jumper cables are so thick) for a relatively short time. The best thing is to use a automatic battery charger used for car batteries which usually has a reverse polarity light on them that flashes or beeps if you accidentally hook up the cables backward. Or hook a multimeter to a known battery , like a AA battery with the positive terminal labeled, and put the red lead of the multimeter to there and the other lead to the other end of the AA battery. If the digital readout is positive 1.5V or so then measure the marine batteries with the same red lead and if the multimeter shows a positive direction then you know you have the positive terminal. If the multimeter has a negative voltage, then you know you have to reverse the cables

Q:highest Temperature i can reach in a lab with electrical discharge i do not care if the equipment gets destroyed or not i just want to know the possibility of the highest temperature you can reach with electricity if there is no limit then simply say no limit. if you know the best possible method please explain as much as possible. thanks in advance.

There is a limit. The temperature of an electric arc (the plasma formed by an electrical discharge) is on the order of 10,000 C. This temperature is high enough to melt any substance known and to vaporize almost any substance known. Of course the amount of heat contained in that arc depends on a number of things like the amperage, the electrical power, and the material making up that plasma. You can produce an arc with a flashlight battery but the heat content of that arc is tiny. However, if you are a group of atoms of, for example, copper, participating in that arc, you are going to melt and some of you are going to vaporize. If you want to learn more about exotic ways to acheive very high temperatures (enough to initiate nuclear fusion), google the Lawrence Livermore National Laboratory and their project on laser ignition for fusion research.

Q:If so, how much?

i'm a retired electric powered Engineer having spent 50 years interior the profession and not in any respect been out of interest can provide, even after retiring. this is a significant field protecting specialisation in electronics, communications, skill, administration, production, administration etc. you will not gets a commission as much as a banker or an accountant in step with hazard yet who needs to easily count type beans? i can assure you've an thrilling time. in case you have an interest adequate, do in simple terms it. you will choose some catching up in physics to a minimum of O point or greater effective a point accepted and your maths will might desire to be good, additionally in case you're actually not very sensible, why do you decide directly to be an engineer?. CEng skill Chartered Engineer and to acquire it you decide on a minimum of a BSc in Engineering with some years of sensible journey in a to blame interest. do not challenge approximately looking a activity, the favorite international will consistently choose engineers of each self-discipline, and the provision is getting much less interior the united kingdom through fact little ones are actually not choosing technological know-how matters.

Q:Can I use an existing outlet in basement that's uses 14/3 wire and tap off of it to wire up a bathroom with 14/3 for light . Fann And one gfci outlet ?

The USA National Electrical Code (NEC) states: 210.11(C)(3) at least one 20-ampere branch circuit shall be provided to supply bathroom receptacle outlet(s). This circuit shall have no other outlets. Exception: Where the 20-ampere circuit supplies a single bathroom, outlets for other equipment within the same bathroom shall be permitted. The basement outlet circuit s not a 20-amp circuit because it is 14/3 rather than 12/3. It supplies something other than a bathroom. You could use that circuit for the fan. For the bathroom outlet, you can tap into another bathroom circuit that supplies only bathroom outlets. Otherwise you need a new 20-amp circuit. Since you are talking about 14/3 wire and a gfci outlet I assume that you are in the USA or Canada. I think that Canadian requirements are very similar. PS Regardless of what you think you might need, electrical code requirements need to be followed. You might get away with something that looks good if you don't need to have it inspected or do it without getting a building permit. However, if you sell your house, a prospective buyer might not be able to get a loan if substandard work is discovered.

Q:i want to know about latest technical electrical machine used in ship's during sailing.Eigther it may be electricity generator or any other equipment.

the newest state of the rt electrical systems on large ships are 'podded propulsion; instead of turbines turning propellor shafts, generators supply electricity to motors that are placed in pods outside the ship, under the hull which turn the propellors.go look up 'Queen Mary 2' on the web for details.

Q:and which one to use in my country Egypt ?

NFPA - National Fire Protection Association - National code that covers anything to do with flamable stuff (electrical, dust, combustibles, sprinklers, fire alarms, etc) (United States) NEC - National Electric Code a.k.a NFPA 70 (NEC is a section of the NFPA code) - Addresses proper installation of electrical equipment, devices and wiring(United States) NEMA - National Electric Manufacturers Association- trade organization for electrical manufacturers. Sets common rules, practices and certification for the manufacture of electrical components and devices (United States) IEC - International Electric Code - International version of NEMA IEC would most likely cover devices made for use in Egypt. I'm not sure what organization or governing body would address the installation there.

Q:I am trying to work with an opamp

Try electronics suppliers such as Mouser, Allied, Digi-key, or Newark
