Q:does anybody know what Transformers 2: Revenge of the Fallen is going to be about? Like what is the whole plot, or storyline?: Sam Witwicky (Shia LaBeouf) discovers something about the origins of the Transformers and their history on Earth. The evil Decepticons need to capture him for information. The climactic battle takes place at the Giza pyramid complex,where a temple is located within. Lorenzo di Bonaventura explained the film will show the Transformers who visited Egypt before the pyramids were built, and all our heroes end up here because of the Decepticons' masterplan. Furthermore, Egyptian hieroglyphs resembling helicopters and other present day vehicles in real life will be explained in the film as being depictions of those ancient Cybertronians who visited Earth. I also read that Mikaela Banes will be Sam's girlfriend who cannot afford to attend college with him.

Q:Transformer ONAN?: Transformer ONAN cooling method for the internal oil natural convection cooling, that is commonly referred to as oil-immersed self-cooling. The cooling mode of the transformer is determined by the cooling medium and the circulation method. Since the oil-immersed transformer is also divided into the internal cooling mode of the tank and the external cooling mode of the tank, the cooling mode of the oil-immersed transformer is represented by four letters. The first letter: the cooling medium in contact with the winding. O -------- mineral oil or ignition of more than 300 ℃ of insulating liquid; K -------- Insulation liquid with ignition point greater than 300 ℃; L -------- ignition can not be measured insulation liquid; The second letter: the way the internal cooling medium is circulated. N -------- The oil flow flowing through the cooling equipment and the windings is a natural thermal convection cycle; F -------- The oil flow in the cooling equipment is forced to circulate and the oil flow flowing through the windings is the thermal convection cycle; D -------- The oil flow in the cooling equipment is forced to circulate, at least in the main winding oil flow is forced to guide the cycle; Third letter: external cooling medium. A -------- air; W -------- water; The fourth letter: the way the external cooling medium is circulated. N -------- natural convection; F -------- Forced circulation (fan, pump, etc.).

Q:I thought the movie was great, but the death of Megatron seems really rushed and just unsatisfying? Agree?: the movies was AWSOMEEE saw it at the cinema, when i got and saw a car i had the feeling it's going to transform into a robot lol :P cant wait for the new one

Q:Transformers are divided into several. What is the role of each? To be specific!: Types and characteristics of commonly used transformers ?????Commonly used transformer classification can be summarized as follows: ?????1, according to the number of points: ?????(1) single-phase transformer: for single-phase load and three-phase transformer group. ?????(2) three-phase transformer: for three-phase system of the rise and fall voltage. ?????2, according to the cooling method points: ?????(1) dry-type transformers: rely on air convection cooling, generally used for local lighting, electronic circuits and other small-capacity transformers. ?????(2) oil-immersed transformers: rely on oil as a cooling medium, such as oil from the cold, oil-cooled air-cooled, oil-soaked water, forced oil circulation. ?????3, according to the use of points: ????(1) power transformer: for the transmission and distribution system of the rise and fall voltage. ?????(2) instrument with transformers: such as voltage transformers, current transformers, for measuring instruments and relay protection devices. ?????(3) test transformer: to produce high pressure, the electrical equipment for high-pressure test. ?????(4) special transformers: such as electric furnace transformers, rectifier transformers, adjust the transformer and so on. ?????4, according to the winding form points: ?????(1) Double winding transformer: Used to connect two voltage levels in the power system. ?????(2) three-winding transformer: generally used in power system area substation, connecting three voltage levels. ?????(3) Autotransformer: Power system for connecting different voltages. Can also be used as a normal step-up or down transformer. ?????5, according to the core form points: ?????(1) core transformer: for high voltage power transformers. ?????(2) shell transformers: special transformers for high current, such as electric furnace transformers, welding transformers; or for electronic equipment and television, radio and other power transformers.

Q:Hello,Recently, my air conditioner broke and I hired a man to come fix the machine. Unfortunately, he did not help my situation and possibly made it worst.Initially, he informed me that my transformer was broken and so said that it needed replacement. However, when he replaced the transformer, both the transformer and the circuit board blew out. Now, he's making me pay, not only pay for his services, but also for the two additional parts. My question is: Is is possible that the circuit board caused this issue? Or did he mess up on the wiring and blow both parts out, by mistake?I just need to know, so I don't pay for something, originally not of my cause.Thank-you.: The Sandshark nailed it. Tell your handy man he's on the hook for the 3rd control transformer AND the 2nd circuit board. Then tell him to hit the bricks. Now do what you should have done in the beginning; call a qualified, COMPETENT technician.

Q:If you have two 12 volt transformers and if we connect their hot wires together does the voltage become 24 or 12 volts?: There is actually a phasing to the transformer windings. If you connect them in series with the phases adding (both hit + 12 at the same instant) you get 24 volts out. If you connect with the phasing wrong (one hits +12 while the other hits -12) and put them in series the output will be zero volts (and they might overheat). If you connect them in parallel with the right phasing you will get 12 volts and the amperage will add to give you the sum of their amperage. If you connect in parallel with the phasing wrong you will get zero output voltage (and the danger of overheating). If the transformers do not make their phasing clear put a voltmeter on the output and briefly turn on the primary while seeing if you get zero or the voltage you want. If the phasing is wring swap the wires of one transformer around and check with the meter again.

Q:I hate feeling the need to justify myself, but I've seen a lot of answers telling askers to do their own homework. I'm trying to do so, but can't find any equations in the book relating power to voltage as well as turn number. Is it PviN? I've just seen Pvi, but that wouldn't apply to multiple loops. This is for ideal transformers by the way, so power for the secondary and primary coils is the same right? But are their vi's equal, or their viN's?The primary coil of a transformer has 200 turns and the secondary coil has 800 turns. The power supplied to the primary coil is 400 watts. What is the power generated in the secondary coil if it is terminated by a 20-ohm resistor?: The turns ratio is 4:1 of the primary. The power supplied to the primary is 400W. So regardless of anything else, in a ideal transformer, 400W is available on the secondary. But voltage will be 4x higher, current 4x smaller, than the voltage and current in the primary. Disregarding all that, if there is 400W of power flowing in the primary, then 400W will be being dissipated in the 20 ohm resistor. Watts in watts out, but secondary load (resistance) controls the wattage. There is no way to tell the output voltage and current, without knowing the input voltage and current. But whatever they are, the product of voltage x current will be 400W, in this instance.

Q:I was just curious if they ever had an episode or something where somebody manipulated a captured transformer and was able to control it or something, or something that turned someone into a transformer. far fetched ya but god knows the stuff that's out there these days, so I was just wondering.: Transformers original series, season 3, Only Human - Criminals get their hands on four Autobots and remove their minds, turning the bodies into piloted mecha. Transformers IDW Comic - Sunstreaker is captured and bootlegged, copies of his body being controlled by humans while they use his original mind as a sort of coordinating system. Transformers Animated - The villain Headmaster's whole schtick is to cut the heads off Transformers and take over their bodies.

Q:i dont get it. at the end of the movie. they did not kill one of the bad guys and he flew off to out of space?? do u think transformers 2 is gonna come out ???: With or without Bay, they will make a Transformers 2. Actually there are a couple still alive. Barricade never showed up to the final fight. Starscream flew out into space. Maybe to go get more Decepticons. Plus who know what other Decepticons were already on Earth that just didn't show up to the fight.

Q:i have fuses and everything that i can use to test my primary but should i add more turns on the primary side? yes i know line voltage is dangerous. yes i have worked with it before and know how to work around it.: 1. I don't see why a power transformer from a UPS would get hot unless it was overloaded or short- circuited, or incorrectly connected. 2. If you are going to power the circuit you indicate, and it requires 12V at 5 A., there are plenty of power transformers off- the shelf you could use to build a power supply with. It would need to be rectified and filtered, for DC output as you require. Possibly voltage- regulated as well? Gets costly Another way would be watch OKorder or similar for a switchmode power supply that does the job (more efficient, less weight). Example: I used 2 computer power supplies I bought brand new, for $A5.00 each, to power a linear RF amplifier that needed 10V DC @ 15A., and a bias supply of -5V @ a few mA. I wired them together to produce 10V DC 26A, using the 5V 26A outputs in series. I only needed to isolate the neg. end of 1 of the 5V outputs from the common ground to get both in series. The bias -5V I derived from the -12V out of one of the supplies, with a 7905 voltage regulator to cut it to -5V. My point is, this entire power supply weighs about 3/4 KG. It is voltage regulated and overload protected, and compact. A standard power supply with output levels like this would be considerably heavier and bulkier, and considerably more expensive.
