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?: Yes, it will suck. As a scientists and former electrical engineer / super evil nerd, I'd have to say from the trailers this whole movie looks bad. I've been looking at the current graphics (i'm also into 3D design with BRL-CAD and Blender) and I would have to say the autobots and deceptacons were made all wrong. Also, something that has been bugging me about the trailers, is that too many humans are appearing in the film. The humans keep talking. They blab. The movie is called Transformers. It's about transformers. It's not like Terminator where the human race is greatly involved. No, in Transformers, a lot of the stuff revolved around Cybertron. A good amount of the time, humans talked little while the robots talked lots. I'd like to say I've watch a lot of Transformer's episodes through the time I've been alive. And as I looked at the trailers, I didn't really see any of the Transformers talk. I saw mostly people talking and yammering in awe and amazement at the fact that transformers are alive. Now, some people are saying the transformers are voiced by some people, and Optimus is going to be voiced by the a former voice person. However, I just don't think it's going to be as great as the cartoons one bit. I don't think the whole urban sprawl bit was a good design. I think the robots were made with too many shades of dark. I mean, look at megatron's design; it's all bad. Also, as I watched one of the actors on Jay Leno, I saw him talking about the movie. He only cited that Transformers is from the 80s. He didn't talk about Transformers in the 90s, 2000s, and other versions of the Transformers. In my opinion, nobody knew what they were doing when they were making this movie.

Q:how could I describe the physics of transformer?: A device by which you can increase or decrease the available AC mains voltage.

Q:I was wanting to buy my little brother a transformer toy, but not one of these cheap ones you buy today, but one you actual transform by yourself like when I was younger. So whats a good website where I can find some for him and me to play with, and I don't really want to spend to much on them, just enough.: Amazon

Q:If you have two 12 volt transformers and if we connect their hot wires together does the voltage become 24 or 12 volts? Please help, thanks so much!lt;3: You asked the same question before. Here is the only correct answer again. 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. As long as the phasing is correct there is no problem with either series or parallel. A lot of commercial equipment is made with two low power transformers because two smaller ones are often cheaper commodities to buy than one special-order larger one.

Q:I have a doorbell that quit working. I don't know how to tell if it is the bell or the transformer: Yes it could be a dangerous situation. A better arrangement would be to mount the transformer on the outside of the panel box through a knockout. Better yet, mount it on a separate octagon box on the wall near the panel. Most doorbell transformers have an option to mount through a knockout on a box so that the 110 volt wires are inside the box, which is then covered with a blank plate. The doorbell wires then connect to the transformer outside of the box so there is no danger of high voltage getting into the low voltage circuit.

Q:Transformer secondary side is high pressure or primary side is high pressure: Step-down transformer primary side is high pressure, secondary side is low pressure. The step-up transformer is just the opposite. Step-down transformer reverse use is the step-up transformer.

Q:I am learning about transformers and one of the items to calculate is the impedance. I need to calculate regular 60 Hz Core and Coil Shell Type Transformers Al wire in secundary, Cu Wire primary and use Epoxy paper for insulation.: It's pretty difficult to calculate the impedances (there's more than one) entirely from the transformer's design data. It's easier and more usual to decide on an equivalent circuit (there are plenty available depending on how well you want to model the transformer) and then to determine the parameters by a mix of calculation and measurement. A pretty basic equivalent circuit which refers all impedances to the primary side, has the primary terminals connected first by Xm and Rc in parallel (the magnetising reactance and core loss resistance) and then by a third parallel branch containg a series connection of leakage reactance Xl, winding resistance Rw and an ideal transformer of turns ratio Np/Ns. Xm is best obtained from an open circuit test but could be calculated as the inductance of the primary winding. For the latter you'd need to know core dimensions, number of winding turns and the magnetising characteristic of the core iron. If you have conductor sizes and conductivities you can calculate the winding resistance Rw, referring the secondary part to the primary by multiplying it by (Np/Ns)?. You can deduce Rc from the losses measured on open circuit at nominal voltage and Rw from dc resistance measurements on the windings. If you know the specific hysteresis and eddy current losses of the core material, you can also have a good stab at calculating Rc. The leakage reactance is quite difficult to calculate from first principles - even designers usually resort to some empirical factors. Basically it's determined from the short circiut test which is at nominal secondary current. The ratio of primary volts to secondary surrent (referred of course) on secondary short circuit will get you close to Xl - you can adjust for Rw which can be determined from the losses on short circuit (core losses are absent here!) or by the two methods indicated above. It's normally Xl that's referred to as the transformer reactance and together with Rc and Rw, the impedance.

Q:Guys can you tell me that how can I calculate transformer winding?Example:- I need (12volts, 4Amps, 50Hz on Secondary's side of transformer and give 230volts 50Hz on Primary's side of transformer) how I calculate the wire's number of turns? In this case I can give different values of current like 1Amp, 2Amps, 3Amps etc on Primary's side of transformer. But I need constant 12volts, 4Amps, 50Hz on secondary. So how can I calculate.Please give an answer with an example basis on (0-12) transformer.: As others said, only worry about the voltage ratio. That determines the turns ratio. Current doesn't enter in to this equation yet. The minimum number of turns on the primary is dictated by two things, the saturation flux density and magnetizing inductance. Flux density is proportional to the applied voltage, inversely proportional to frequency and effective area of the core. You'll need to know the saturation limits for the core you are using. You also need to have a minimum numbers of turns to minimize the no-load current which relates to magnetizing inductance. My rule of thumb is the inductive reactance must be 5x the maximum expected load resistance, however, for a AC mains transformer, this is often a hard number to quantify since the load can be near zero. Next is wire size. You will need to consider proximity effect losses as well as DC losses. You'll find that there is an optimum wire size for the windings, but for a 50Hz transformer, you'll probably use a wire diameter smaller than optimal for a low power transformer. I suggest reading about this in Ferrites for Inductors and Transformers by Snelling and Giles. You may need to make compromises to meet your needs. This is where the current supplied by the transformer comes in to play, maximum heat loss expected. While making your own transformer is educational, for power mains transformers, you are better off buying one or scrapping it from an old piece of equipment.

Q:Do you think transformers is a good movie?Whos your favourite team autobots or decepticons?Whos your favourite transformer?And whats the best scene in the film?: Not bad.My brother is intersted in it very much.

Q:High-rise residential basement transformer noise is too large, how to solve, whether the need to shift, there is no other way to solve! Thank you as much as possible! If you have to do this project also please educated us!: Since it is installed in the basement of high-rise residential, the transformer must be dry-type transformers. First check the fasteners on the transformer and re-tighten if loosened. Especially the core of the upper and lower clamp, if loose, can not clamp the core noise will be significantly increased. In addition, if the installation of the foot is stable, etc. also check it. Note that the transformer must be de-energized when checking and tightening, and then ground properly. If you really can not reduce the noise of the transformer itself, take sound insulation measures can also have a very significant effect. For example, in the transformer room wall paste sound-absorbing panels. Or install a cushioning rubber pad underneath the foot of the transformer. If you want to achieve better results you can use a special shock absorber to the top of the transformer, so that it does not directly contact the ground. Can play a very good sound insulation effect (using the above sound insulation measures, basically can make the transformer room next door noise reduction 5 ~ 6dB, or even better)
