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?: My ONLY issue with the movie is Bernie Mac. I can't stand him. I wanted/knew Ghost Rider was gonna rock but then it turned out that it was the worst movie I've seen in 2007. I watched the trailer after seeing it realized the montage in the trailer were just boring and empty scenes but in the trailer for Transformers, it looks like they have too little time to squeeze so much (good) stuff into the movie. If you've seen the Island and liked it than you'll like Transformers as well. Trust me, Transformers won't be a dissapoint ment but it maybe considered the best summer blockbuster to the majority of Americans. (Since Pirates sucked and Spider-Man could've been better)

Q: 150KVA transformer can withstand much power, how to calculate: 150KVA transformer load capacity is (150 * cosa) KW cosa is the load power factor

Q: i have plenty of 3 phase 220 in my shop, but one of my machines requires 440 3 phase. i was going to use a 75 kva transformer with 440 primary 220 secondary in reverse to supply the machine. it is a 15 hp motor 40 amps. i figured my minimum kva requirment to be 37.5 but more cant hurt for the potential high cutting rates i may need to achieve. i simply wanted to buy the transformer, hook the 220 3 phase supply to the primary, and the output to my machine. I think this will provide me with 440 output. the motor plate says 7-1/2 hp/15- hp. 40/20 amps. Any help is welcome, i hate to buy the transformer and not have this unit work. i would change the motor wiring, but the diagram is gone, and the wires are not numbered, also i believe id have to change all the heaters, which are hard to come by, as well as various other parts in the panel. just seems the transformer is the easiest way to get this machine up and going in prouction.: The main disadvantage of using a transformer with a motor is the high starting current in the neighborhood of 600% of rated full load current. The transformer impedance will cause a significant voltage dip on the secondary of the transformer when the motor is coming up to speed. Using an oversized transformer will probably take care of that. If this is some type of cutting tool, I assume that it is never started with the cutting head in contact with the load. That will also help. Edit 1 You should also consider provisions for grounding the load side. The secondary should be wye connected so that you can ground the neutral. That means that you should buy a wye-wye transformer so that you can use the low low vlotage side as the primary and still have a wye secondary.

Q: An AC adapter for a telephone answering machine uses a transformer to reduce the line voltage of 120 V to a voltage of 8.00 V. The RMS current delivered to the answering machine is 570 mA. If the primary (input) coil of the transformer has 600 turns, then how many turns are there on the secondary (output) coil?What is the power drawn from the electric outlet, if the transformer is assumed to be ideal?What is the power drawn by the transformer, if 13.5 percent of the input power is dissipated as heat in the coils and in the iron core of the transformer?: Ns/Np Vs/Vp Ns (8/120) * 600 40 turns P Pp Ps Vs * Is (an ideal transformer) 8 * 0.570 4.56 watt 13.5 percent of the input power is dissipated, then the power from output coil (100 - 13.5) % 86.5% of input power. ---Po 86.5% Pi 4.56 0.86 Pi ---Pi 4.56/0.86 5.30 watt

Q: I want to get the asus transformer, and on the web, there is stuff like asus transformer prime, and i want to know the differences between both and the negatives and positives of each. Asus transformer prime is $100 more than the asus transformer, so I want to know if it's worth it or not. Thanks!: Yes the transformer is different and older than the transformer prime. It has NVIDIA Tegra 2 processor vs the tegra 3 in the prime. Tegra 3 is a quad core 1.3 ghz processor and the tegra 2 is a 1ghz dual core. You should definitely get the prime but dont buy it yet. ASUS sold out the first batch which had a few issues, and they are releasing the bugs fixed second batch soon with Android 4.0 Ice Cream Sandwich pre installed (I could be wrong here), so wait till then and buy it with the keyboard dock which doubles the battery! I'm waiting for the prime to come out soon too! It is very thin and thinner than the galaxy if not the same. Hope this helped.

Q: Do you know what that show is called where there are these dinasaurs, and there are good oens, and bad ones, very similar to transformers.The dinasaurs transform into robots. Whats it called?: I remember a purple dinosaur too. I'm pretty sure it's called Beast Wars, and it is a version of Transformers. If I remember correctly, the Autobots and the Predacons landed on Earth and in order to survive they took form of existing life forms on Earth. The Autobots took the form of mostly animals, but the Predacons landed near some dinosaur fossils so some took the dinosaur shapes. Megatron was a purple-ish T-Rex, and I think there was a pterodactyl one too. Optimus Primal was a gorilla and they had a cheetah and a rat in the Autobots.

Q: I have a transformer scavenge from a VCD player, written 25W on VCD player, so that should be the transformer's VA rating ?I also measured the transformer, it has 2 secondary. It have 11.1VAC on 1st output winding and 13.1VAC on 2nd output winding.So if I were to use into DC (rectification) and calculate for other maths, should I use the value of 11.1VAC / 13.1VAC, or their average which is roughly 12VAC ?: nicely the voltage could desire to be smash up around the resistors (as resistors in sequence artwork as a voltage divider) with a million/11 going around the 100ohm and 10/11 going around the 1kohm, so i could anticipate look on the 0.4W resistor. With R of one thousand and P (max vigour) of 0.4 you need to use the equation ( P VI or greater, PV^2/R) 0.4 V^2 / one thousand 4 hundred V^2 V 20V

Q: Will the 250KVA, 500KVA, 630KVA Van transformer size,: Box transformer inside the configuration is not the same, the size will be different, which factory production size is not the same

Q: How does a transformer effect amplitude modulation in an am transmitter. i would really love this to be explained from the basics as i am not so advanced in electronics. but i would really like to comprehend how this happens form the basics. thank you: Read this.

Q: Is the transformer a power adapter?: No, the transformer should be a device that performs impedance matching in order to achieve maximum power transmission. In turn, "power adapter is a transformer" is also unsatisfactory, at least the general power adapter contains a transformer. As a power adapter requires a common power supply into a device required power, voltage, current, impedance and other aspects of the match, of course, it needs a transformer. Since it has the function of changing the voltage, call it "transformer" is no harm. I would like to say that the power adapter is not only transformer, it needs to achieve in addition to the voltage other than the parameters of the match, for example, the most simple general-purpose DC adapter in addition to transformer that there is a "rectification" process. The transformer, narrow sense that it is just a component only, like resistors, capacitors, transistors and so on.
