Q: I am confused about this figure because some equipments have 230 Volts AC (50 Hz) specified as their operating voltage while some others have 240 V AC (Hz). I practically measured the supplied voltage. It was something like 235 V AC. So I am confused about the standard figure. Is it 230 V AC or 240 V AC ?: Power in the US is 120 VAC +- 5% so 114 to 126 is within tolerances per the maintenance people who were fixing a high voltage at my place. I used to measure 117 at my house. People often say we have 115/230 for our single/double delivery voltages. Most equipment with a range printed on it says 110-125. India presumably is nominally 240.

Q: I quest it will be a big surprise to everybody. a) He will make a big party on earth. b) It will be a new beginning. c) It is the end of the happy moment on earth.: Do you know what EMP is? One nuclear bomb, exploded about four hundred miles in the upper atmosphere, and every piece of electrical equipment within a thousand mile radius gets fried. No more phones, no more internet, no more cars, no more electricity, or television or radio or refrigeration. Are you ready to have your world rocked? Before He returns, this world is going to experience the most terrible times the earth has ever seen, and it has seen some pretty dire times. 21 For then there will be great distress, unequaled from the beginning of the world until now—and never to be equaled again. 22 If those days had not been cut short, no one would survive, but for the sake of the elect those days will be shortened. 23 At that time if anyone says to you, ‘Look, here is the Christ!’ or, ‘There he is!’ do not believe it. 24 For false Christs and false prophets will appear and perform great signs and miracles to deceive even the elect—if that were possible. 25 See, I have told you ahead of time. 26 “So if anyone tells you, ‘There he is, out in the desert,’ do not go out; or, ‘Here he is, in the inner rooms,’ do not believe it. 27 For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man. Matthew 24:21-27

Q: I have an 01 impala and theres some equipment in the trunk on the drivers side. what is it for?: jack or jack tools

Q: I have a hot tub connected to a fused disconnect. That is fed from a 30 Amp circuit breaker in my main panel. I was told that i needed to have it protected by a GFCI breaker. Would it satisfy the NEC if i just replaced the current 30 amp breaker with a 30 amp GFCI breaker and left the disconnect between that and the hot tub?: Codes are different in different areas. Where I am changing the breaker to GFCI is acceptable IF the tub is on a dedicated circuit.

Q: I accidentally connected the negative and positive terminals of my battery with a wrench, I have checked all the fuses and none look to be blown. What else should I be looking for?: Make / model and year would certainly help us help you.That must have been a big wrench to reach that far across those terminals.Hope those burns from the wrench and battery explosion are doing well. If you shorted a battery with a wrench? ( unlikely) or if you crossed booster cables, then you would have a big spark. Some burn your favourite tools . Some burn your cars computer, and a few other parts

Q: I am studying in college to become an electrical engineer but there is one problem, i'm almost clueless about what i'll do once i graduate. like at what kind of companies and places will i work at? what will i be doing? whats it like to be an engineer? what will be my dutys?. and also how much does an engineer (more specifically the kind in my field) earn? really need to know this. thanks: I okorder

Q: [Location no object] Can anyone give me the details of three electrical energy suppliers that offer the best value for money? And any additional details about the company(Website etc)Thank-you!: Go to the DOE site. Search for electric costs. It gives the cost of grid power for the entire country. There is also a lot of information on type of power, etc. Looks like Washington, West Virginia, and Kentucky have very low rates.

Q: And what is an MBA? My sweetie is studying that at a community college will that mean he won't learn as much as if he took it in university?: Electrical engineers are interested in the control and utilization of energy. This energy can be in the form of electricity, which is the flow of electrons, or in the form of light, which is the flow of photons. There is a duality between energy and information and, as such, EE's are very interested in how information is transmitted, transformed and stored. Electrical engineers design a broad range of devices and systems from electrical power grids that supply homes and industry with electricity to systems that deliver telephone, radio, television, network and space communications. EE's design the computers that affect almost all of our modern lifestyles. EE's are responsible for the microprocessor systems that control toasters and microwave ovens, automobiles and guided missiles, toys and space shuttles--just to mention a few of the myriad of applications of these systems. Then there are other areas a EE can get into like instrumentation. It can not be narrowed down to one thing.

Q: I have been trying my best to put some few things together as per building electronics and electrical equipment but i really lack circuit diagrams that can put me through. i presntly need a circuit diagram of an inverter with atleast 20kVA output.: There is one very important thing missing in your question: What will be your DC input voltage? Because you can forget 12Volt . you would need 2,000 Ampere from your battery to achieve 20kVA @ 85% efficiency! Most inverters I know in this league have between 350 and 600 Volt DC input.
