Q:A want to know what happens to transformer when it is overloaded. Where i can get information about this: A transformer is just like any other circuit. The only difference is the primary of the transformer induces a current and voltage in the secondary without a direct electrical connection. But the induction comes from the collapse of the magnetic field in the primary which induces a current in the secondary. That current generated in the secondary follows the same laws as any other circuit. If you overload those terminal wires or short circuit it it will overheat and melt the wires possibly if you don't have it fused protected. In fact they make induction furnaces which are just transformers with the secondary that forms a short circuit in the coil. The temperature gets hot enough to melt iron and non-ferrous metals just from the heat of the short circuited (overloaded) secondary coil. Transformers are the same as any solenoid or electromagnet with AC electricity. So if you can't find info directly on transformers, then just use coil formulas for AC circuits

Q:I think it will. Michael Bay who doing the movie has a history of messing up classics. Godzilla is my prime example. So, what do you think? Transformers the movie: Good or Bad?: Well, unfortunately you have some facts wrong, so chances are you may not like the movie you are going to see, because you are not sure what movie you are talking about. Godzilla was directed by Roland Emmerich of Independence Day fame. Michael Bay did not direct that movie. MIchael Bay has been associated with much better movies such as Armageddon, The Rock, Bad Boys and Pearl Harbor. Okay, maybe Pearl Harbor wasnt that good, but the rest of them are a hell of a lot better than Godzilla. About Transformers, no, it will not suck. See, there is someone else involved in the movie who wont let it suck. Steven Spielberg. With those two involved, and yes I realize that Spielberg is only Executive Producer but he is still very involved, this movie is going to be great.

Q:Devices that convert the car battery's 12 V DC into 110 V AC are easily available. The conversion from 12 V DC into 110 V AC is done in 2 steps. One circuit in the device changes DC into AC and transformer changes the voltage. Does it matter which step is done first and why?Any help would be awesome! Thanks!: transformers do not change DC values. Do not hook a transformer to DC. Depending on how the connections are made, it may be a short circuit.

Q:The specific steps and procedures for installing the transformer: Oil-immersed or dry-type transformers are generally installed by the engineering team or factory installed do not know how much capacity your transformer is electronic or industrial power system

Q:!!! I took a cardboard cylinder from a used firework, dug out all the crap, wrapped 160 turns of tinned copper wire on the outside tight and evenly so it is a beautiful solenoid, held it in place with 2 rubber bands. That was the secondary. Then I wrapped an insulated steel wire around a screwdriver shaft 10 times, stretched it out a little inserted a chopstick into this primary and inserted the chopstick into the firework. I then held it all in place with tissue paper and tape and wired the primary up to a pulsed DC circuit which was made of 3.0 volts wired to a steel file which I rubbed the electrode across. The secondary was wired to a current detector but I got no signal! Why is there zero inductance in my transformer and why is there no current at all? It can't even light up a small lightbulb!!: Capital and minuscule letters are differentiated in the Roman, Greek, Cyrillic, Armenian and Coptic alphabets. Most writing systems (such as those used in Georgian, Glagolitic, Arabic, Hebrew, and Devanagari) make no distinction between capital and lowercase letters, a system called unicase. Indeed, even European languages did not make this distinction before about 1300; both majuscule and minuscule letters existed, but a given text would use either one or the other. In alphabets with a case distinction, capitals are used for capitalization, acronyms, and emphasis (in some languages).Capitalization is the writing of a word with its first letter in uppercase and the remaining letters in lowercase. Capitalization rules vary by language and are often quite complex, but in most modern languages that have capitalization, the first word of every sentence is capitalized, as are all proper nouns. Some languages, such as German, capitalize the first letter of all nouns; this was previously common in English as well. (See the article on capitalization for a detailed list of norms).

Q:I have an an iPod touch with 3.0 and I installed a jailbroken app called Transformer. It makes thr iPod look like an iPhone. But when it resprings, nothing changes. Please Help!: I feel your pain, but Transformer only works on itouches with the firmware 2.2 or under. If your still want a iphone look-a-like this is what I did and I works great Maybe even better than tranfromer!: 1. Download iCall, textPlus, and Flicket off app store. 2. Download CompassF app off cydia. 3. Download theme iPhoney theme off Cydia 4. Download Better 3G WiFi (turns wifi bars into 3g) 5. turn on the 2 themes ATT bars will be added w/ iPhoney automadiclly 6. Download SBSettings, extras, and turn on the numeric battery. (like 3Gs) 7. Lastly, if you want to go that extra mile Im working on a Theme that changes the iTouch settings to iPhone ones with wallpaper on main page. And thats it, the Icons and names of the 3 app store apps should change to camera, messages, and phone. The spotlight should say, Seach iPhone and thats pretty much it. Not only does the phone work with wifi now looking just like the iphone dialpad, and so does messages. So I think this is better than Transformer and wont mess up ur touch like transformer would. Hav fun messing with your friends minds lol! :)

Q:A speaker with resistance R is rated at 16Ω. What ratio of NP:NSof the transformer is required so that the stereo thinks that the speaker is 8: The impedance ratio is the square of the turns ratio, so to transform a load resistance of 16Ω to one of 8Ω you need a turns ratio of NP/NS sqrt(8/16) 0.707:1 This relationship arises as follows - In the ideal case, the flux in the transformer core can be taken to be the same in the primary and the secondary, so by Faraday's law of electromagnetic induction VP/NP VS/NS where VP and VS are primary and secondary induced voltages. For conservation of energy, the power in the secondary circuit must be the same as the power in the primary circuit (assuming no losses in the ideal case) , so (VP^2)/RP (VS^2)/RS, leading to - VP^2/VS^2 (NP/NS)^2 RP/RS Note that stereo systems are incapable of thought, so the question, as asked, is meaningless, or at best fanciful; the appropriate language to use is 'what transformer ratio is required to present a resistance of 8Ω at the primary terminals when a resistance of 16Ω is connected to the secondary ?'. This draws attention to the fact that the transformer/load combination will behave in the same way whatever it is connected to - the 'thoughts' of the stereo are irrelevant .

Q:I bought my first ever Transformers toys which are the movie line, Ironhide and Barricade. However it is noted on the side of the box classes name; Voyager and Deluxe. What is the difference between both? I've search around the internet but none has given definitive description about it. All I know is that there is Deluxe, Voyager, and Leader class, and some more lower grades.Does the classes defines scale, size and complexity of the transformation?: Transformers Leader Class

Q:Find full load current of transformer. What do it mean by full load current? 100% efficiency, or maximum load in secondary winding?Let R1 32ohm, R20.05ohm, X1 45ohm, X2 0.06ohm.1 is in primary and 2 in secondary winding.R0250kohm, Xm 30kohm(R0 and Xm are the values refered to primary)How to calculate the full load current?: there are many criterion it is application dependant or power it is the load that causes a temperature rise that if loaded beyond it will cause failure of course it depends on the insulation material so a smaller transformer could have a much higher rating because it can stand more heat small electronic stuff will generally be when the transformer can no longer sustain the output voltage Anita

Q:i want to know the actual lyrics for the Transformers theme that was re-covered by Mute Math. i heard that they changed some of the lyrics but i would like to know the exact changes, thanks.: Whoa she just gave you the best answer!!
