- 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'm a fresh grad licensed electrical engineer. Which field in electrical engineering job should i enter? for example, in construction, in manufacturing of electrical equipments in substations and the like, in distribution utilities/gencos.
- gencos
- Q: i want to make a bulb on and off at intervals of say half an hour. readymade timers available in shops(india) costs much and does not support shorter intervals like half an hour. any cheaper electronic circuit which can do this control? from where can i get the circuit or its diagram?
- Depending on your skills, a CMOS 555 timer chip could probably drive a solid state switch (triac) for this interval although a more reliable timing, especially if you want exactly a 50% duty cycle, by feeding the timer output into a counter, so that the 555 cycles say 32 times (once a minute about) for each change of state of the selected output. Smaller cycle times are more stable.
- Q: Any tips for a rock band that will be playing shows in the next month or so? Set-up, breakdown of equipment, working the crowd, preperation, etc?
- Learn to put up and break down your equipment quickly. I've seen a drummer take 30 minutes to set up the most basic of drum sets when the set was brought in. Have backups for your guitars and electrical equipment. A broken string on a guitar is a 15 minute pause on your set (experienced that from the same band that took that long on the drum set) to fix it. Ignore the crowd if you think they are bored (in music videos those crowds are paid to be all festive, but they are no where near that in real life). If they aren't paying attention to you, you can forget the onstage talk and sing alongs. Ignore the drunks (talk with the manager before hand on having the manager remove the noisy drunks). Have your merchandise (same band above forgot their stuff and I wanted a CD)!
- Q: I bought some electrical equipment at a cheap price but it was due to a discount error.I placed the order and recieved the confirmation.Can they refuse to send my the products or change the price?Your help is much appriciated.
- Depends on what you mean by discount error If you used a promo code that is not supposed to be valid on the item you purchased, then NO, he does not have to honor your order just because the system accepted it. On the other hand, if he has the item listed incorrectly (ie, $10 instead of $100) than yes, he should have honor it. Make sure to look for anything on the website that says something along the lines of prices subject to change which could be used as a loophole. Either way though, he may not charge you more without your permission. In Califonia, if an item in a store is marked a certain price, it is actually illegal for the store to try to charge you more when you attempt to purchase the item. However, based on the fact that you may not even be in the same state as the store, things get a little murky. The best answer is simply to cross your fingers, as the internet is really a grey area. UPDATE: In follow-up, no they absolutely cannot demand that you send it back after you've receieved it. Nor can they try to charge you more afterwards. If it gets shipped, then it's yours to keep!
- Q: I sold a small bit of electrical equipment to a guy in Norway - I'm in the UK.Item became faulty after a month - I said I would refund him but I had spent the cash already and couldn't repay him back in one go. Item was returned.He agreed that I could pay it up ?899 over 4 years as I'm just a student and not working full time. It was sent in his currency and ?899Trouble is he is now claiming I've not just to pay ?899 back but the amount is to be much more in GBP's as the pound as got weaker against his currency although he stated he wouldn't add any interest on. Any advice?
- Well it isn't your fault that the currency is more or less. Do you have anything in writing? You may want to check what laws are on the books but he can't just change the price on you
- Q: All of my US electrical equipment has had it's wattage determined to provide the proper transformer to use. Transformers were bought to support between a third and half of the load that would be demanded. I am not using multiple devices which would cause overload. My TV (395W) only clicks once (like the sound of a relay) when plugged into the 3000W 220-120 step down transformer and never turns on. The transformers are tripping the breaker of the apartment now. I was assured there would be no problems taking my US equipment to Amsterdam and using transformers. Some light on this subject would be appreciated. I can't imagine everyone has this trouble, or there wouldn't be companies in the US in this business.
- In case noone else has a better answer, this might be something to think about not sure if it is correct TV's especially, require the 60Hz frequency of the electricity in order to work properly if the Amsterdam power runs at a different frequency that might be the reason. Transformers convert the power (wattage) correctly, but not all transformers will convert to the correct frequency most transformers will convert wattage at the frequency they are plugged into If this IS the case, you need a wattage and frequency converter for your tv to work again, I may be wrong
- Q: for example, a 3ds?
- Never heard of 3ds? DVDs - dish soap water. Dry with clean cotton towel. Does not work? Buy a new one.
- Q: Examples include-Unplug your wireless router for 30 seconds and then plug back inUnplug all elerical cords for 45 seconds then plug back inWhy do they recommend a specific amount of time?
- Most things today have a computer in them of some sort and sometimes things just get messed up inside them. Unplugging them allows them to reset to factory standards and they usually work after that. I never wait a specific time like they say. Usually 5 seconds at most is enough to reset everything. They tell you longer times to cover their bases and in rare cases it may need that much time. Most electronics have a transformer in the plug, that's why its bigger than a normal plug and it takes a little bit to use the electric stored in them.
- Q: I am doing some work and i just couldn't remember the piece of equipment, that hospitals use to bring people back to life by using an electric shockThey have Pads on them and are often used in films.Thankyou in advance,Babyx
