Q: I saw something about people who have problems with electrical equipment. Also lights flicker or go on and off or dim. The devices either will not work or act strangely for no apparent reason. There is nothing wrong with the equipment because it will work fine for any other person. There is a metaphysical term for people like this. They also tend ot hear static or voices when tv/radio or computers or off. It has to do with some kind of extra sensory. I am not completely sure though. Does anyone know anything about this? What does it mean?: Hi Ditto. There is a school of thought that believes all living and non living things have their own electrical properties or spheres. Each individual is classified as living thing hence has his/her own electrical property. Sometimes his/her electrical property vibrate on the same frequency with other electricalelectronic devices in his/her vicinity depending on that person state of living. It's usually a temporary state of an affair which will pass eventually.

Q: Garbage disposal is wired into open electrical outlet down thru basement. Dryer is not vented outside, which is in the basement also, right next to this outlet. There is excessive lint from the dryer all over this open outlet that doesnt have a cover and the live electrical big thick white wire that you wire a house with is split down the middle then the raw metal part is inserted into each side of the outlet for the garbage disposal. If I pull this out to disconnect it will it spark? Shock me? Catch on fire? I want to do this because I am afraid it is going to catch on fire from all the lint. Is that possible also?I rent and I know the dryer should be vented, however it is all glass block windows and landlord has yet to fix it so please dont tell me to vent the dryer. thanks: vent the dryer.important.

Q: 1. Why is it important to keep this equipment free from excess oils and product build up? Many thanks :): Your irons? They should not have build up on them because it could burn the hair and hamper the way the irons work

Q: examples of electrical equipment in which insulators and conductors are used.and give reasons for their usethxthe one that answers will get 10 points: insulators are used on wires and places you don't want electricity to flow conductors are used in circuit boards and almost every electrical component. conductors are used to carry the flow of electricity.

Q: I want to run an appliance that uses DC 5V 2.5A at 6 watts consumption using an adapter from the cigarette lighter socket. I have a standard 12v car battery in the small car. Do i need to get a bigger battery/more batteries, special alternator, or something else to run this appliance permanently?Is there an online calculator to help me work out how much battery power i need?Many Thanks to all answerers.: First, 5 V times 2.5A equals 12.5 W, not 6 W. I'll assume, therefore that 6 W is the average, but the peak may be 12.5W. Also, assuming no conversion losses by the adapter, 12.5W in 12.5W out. Since the socket delivers 12 V, you're looking at about 1A peak. To a second approximation, divide by the adapter's efficiency (I'd guess 85%) to find out what's drawn - might be just shy of 15W. Most sockets have a current or power rating. My car says 120W, 12V - which translates to 10A. If you can't find the rating, check the fuse rating. It's probably 10 or 15A. If your car socket has the same rating as mine, you could run 8-10 of your appliances with no problem, all at peak, and 20 of them on average.

Q: charges, what other taxes, charges etc am i obliged to pay to stay within the law??: Thats a reflect of the IO interface. Same with me too

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: Also, do students studying to become either one of these need to study things like how to program an java and stuff?: electrical engineer deals with electrical equipments(like motor,drive,plc),automation process etc and a mechanical engineer deals with mechanical equipments (like compressor, refregeration,air conditioning engine etc) both of the engineers need to know programming language. but it is not necessary to learn java

Q: I mean for SF6 (gas) containers used to refill electrical quipment such as circuit breakers, must the container be discharged completely, or is it possible to retain a partial amount of SF6 gas in the container for future refilling activities? Any electrical experts out there, would really appreciate your assistance with this. Thanks!: Check the MSDS sheet for safe transport. Is a seal broken before use? Do the containers get returned after use or are they discarded (how?). Your local power company must have info because they use this stuff at switching stations.
