Q: I have an item that is magnetic and it was accidentally heated. That took away a lot of the strength how can I restrengthen my magnet?: Strengthen A Magnet

Q: I have a 2000 Monte Carlo SS that is stock, as in no aftermarket radio/electrical equipment and the fuse for the a/c and cruise. I noticed it popped when I bought the car and each time i put the same size fuse in or a bigger one, it automatically pops. I pulled the dash apart and all of the connections are good so I'm not sure of where to go.: Need to know which fuse exactly is blowing. Never EVER install a larger fuse, good way to melt the wires If the fuse blows when you turn on/off the A/C compressor, usually the diode is blown which shunts the voltage spike. some of those are inline near compressor while others will look like a fuse but black with an arrow on top of it

Q: I have two orange electrical outlets in my dorm and I want to plug things like my lamp, fan, phone charger, etc. into them. Is that safe?: Orange receptacles are Isolated ground, meaning the ground hole on the receptacle doesn't mechanically connect to the mounting yoke, typically used for computer circuits. A ground wire has to be directly attached to the ground screw even with metal conduit systems. They normally also have a green triangle. amzn.to/1Nsbgyv They are designed to isolate the ground from equipment that could create electrical noise on the ground, you shouldn't use it for things with motors. I have also seen some receptacles that where an odd color of red, that almost looked orange. amzn.to/1Nsbohu Red is the designation for emergency power. Small items like you mentioned should not be a problem, would be good to use for clocks with critical alarms.

Q: I am an electrical engineering student ,but I dont know what to do when I graduate. I like music and I want to do something with music. I have heard of audio/sound or acoustic engineering, but I don't know exactly what an audio/sound or acoustic engineer does.: Audio is a field that many EE's get into. Focus on digital signal processing and/or amplifier design (analog circuits), and see if you can find a class from the physics department on acoustics. Auto-tune was developed by an electrical engineer working for an oil company -- the guy was working on frequency quantization to make it easier to interpret the results of ground-pounding measurements, when he realized the technique could also automatically fix pitch problems in voices. Typical salary for EEs start around $60k/yr.

Q: I understand that the frequencies emited from cell phones can interfere with the electrical equipment in ICU's; however, why can't patients have regular phones in ICU's; regular chord phones shouldn't emit frequencies or do they?: My mom was just in cardiac ICU and they did let people use cell phones as long as they were on vibrate. It was annoying though, so many people chattering away when there were some very sick people in there trying to recover from surgery. Hospitals are noisy enough and it was hard as it was for my mom to sleep. I took my phone calls out to the hall. My mom could call out if she wanted by asking the nurse and we could call into the nurse but not call in directly. That was best so my mom could get some rest. Phones aren't apporpriate everywhere.

Q: I have a garage full of my dad's old equipment from oscilloscopes, amplifiers, circuit board materials, etc. that I don't know what they are/or are worth, or how to go about selling. Does anyone have any suggestions other than listing everything individually (there is a lot) on OKorder or CraigsList? I'm leaning towards hiring someone to come in and auction it all off for me, but need suggestions.Thanks!: Perhaps try an OKorder seller, or let a friend or relative put it on OKorder. It is quite a bit of work to sell on OKorder properly, but if you give then half the proceeds, you both might win! Another approach is to bring it to a large city electronics swap - all kinfds of electronics geeks come to these and you will gets lots of advice on value.

Q: Conduct regular maintenance tests for the electrical equipment.The following actions should be taken to reduce the probability of potential electrical deficiencies at this facility.The Hazard: potential electrical deficiencies means the possibility that this facility will not work due to electrical problems in other words, future problems caused by lack of maintenance on the electrical equipment. Therefore, the sentence could be rephrased as follows: The following actions should be taken to to make sure all the electrical equipment stays in good working order.

Q: I have heard from a lot of people about the greatness of an EE degree but never got the chance to ask why? So what is so cool about an electrical engineering degree that makes it better than the other engineering degrees out there?: You learn about Electrical Engineering.LOL Check this out

Q: 2)Please do include the details as to why does spark devlop wn connection at one end is loose. 3)How the +ve electrode retains itz polarity though it accepts the electrons continuously, in a closed circuit.: 1) For laymen understanding, electrical grounding is a protection of your house against lightning, instead burning your house or someone inside your house gets fried. In your appliances, electrical grounding protects you from getting electrical shock in case one of the electrical wire touches the metal body of your appliance. Now on electronic grounding, it is a protection of a certain circuitry from getting damaged by an electrical charge from your body in case you touch it. 2) Electrical wire connection is like a water pipe connection. Electrical current passes through the wire while water current passes through the pipes. If there is a loose connection of a certain electrical wire, or loose pipe connections on your water pipes; The loose pipe connections will produce leaks while the loose electrical connections will produce sparks. 3) It always retain its polarity always. Just like magnets, it retains its polarity, north and south. Electricity is based on magnetism. Law of nature.

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.
