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: explain the difference between an insulator and a conductor: The main difference between the two, other than a conductor conducts both heat and electricity where is an insulator does not, is the number of electrons located in the outer shell. A conductor has either 1, 3, or 5 electrons in the outer shell. Both copper and silver has only 1 electron in the outer shell. This is why copper is used in house wiring. A insulator generally has either 4 or 8 electrons in the outer shell. Carbon, which has 4 electrons in the outer shell, is a fairly good insulator. This is why carbon is used to make resistors.

Q: I don't understand how oil and gas industry has anything to do with electrical engineering jobs??Am I not seeing this because currently I am working as a electronics engineer ? This is how I am thinking about this - Oil and gas industry , digs up oil , provides it to our cars and trucks so they can run. Now I don't understand how or where Electrical engineers come into play into this ?? Please make me understand. I want to know.P.s: I am an entry level electronics engineer, with a degree in Electrical engineering , Currently I am located in Houston, texas.: This website will show you jobs in your discipline in the oil and gas industry. Take a good look at the descriptions to find out what the work could involve, and follow a trail on the internet to see where you could use your skills in your local area. You will need to think about travel at some point though, in this industry.

Q: i am in college and my friend tried to explain his major in electrical engineering but i am not completely sure what an electrical engineer does.: Involved with generation, transmission and distribution of electricity, use of electrical equipment like furnaces, motors etc. Repair of machines, Design of electrical equipment etc.

Q: I dont understand how charged particles in the sky would effect the electrical system down here.: It couldn't. Solar flares happen on the Sun. Some solar flares trigger coronal mass ejections (CMEs). If pointed in the right direction, some CMEs reach Earth. Most CMEs are deflected harmlessly by the Earth's magnetic field, causing auroras. Approximately once a century, there has been a CME powerful enough to penetrate the Erath's magnetc field on cause induction in electrical grids: telegraph lines in 1859 and Hydro-Quebec's transmission lines in 1989. Now that we are aware of the problem, warnings are issued and precautions are taken.

Q: hiwhenever there are clouds, lightning or clouds sparks strikes my house and damage my electrical equipments like tv, fan, lights. my house has an entrance from south side and have windows, doors openings from this side, i also have openings in north direction to access to my back verandah but no sparks fall from this side. The house have 3' high iron bars fencing at front wall of 5' height as well as on rear wall of 5'-6 height. Do i need to put one 1'-6 high lightning rod made up of copper and aluminium and placed it on the roof top of my house to arrest these lightning sparks whenever they fall or some lightning arrester or you have any good solution of my problem. my house is 39' wide and 52' in length and 33' high(including ground floor,first floor, second floor) and have flat roof top and its in haryana region. please suggest me what to do? i will be really grateful to youthanksbye: You Have the answer in your question you basically have to use a lightning arrestor an top of your house. But make sure that the earthing of it must be separate from your house earthing and try to maintain a earth voltage around 1Vlts preferably below 1 Volt. For more information on lightning arrestors go to the link below.

Q: I am just a few classes away from getting my Associates in Electrical Engineering. I currently have a Diploma in Industrial Electricity and have been working in industrial maintenance for 12 yrs. and am currently an electrical technician (10 yrs. multi-skilled and the last 2 yrs. strictly electrical due to a job change). I have returned to school to get my AAS in EE, so I would really like to know what possibilities I could expect.: You can get a job as an electronic engineering technicians. You help design, develop, test, and manufacture electrical and electronic equipment such as communication equipment, medical monitoring devices, navigational equipment, and computers. You may work in product evaluation and testing, using measuring and diagnostic devices to adjust, test, and repair equipment. Median annual wages of wage and salary electrical and electronic engineering technicians were $53,240 in May 2008. The middle 50 percent earned between $41,550 and $64,120. The lowest 10 percent earned less than $32,490, and the highest 10 percent earned more than $78,560. Median annual earnings in the industries employing the largest numbers of electrical and electronic engineering technicians were:
