Q: How do transformers work detailed descriptions please. Also how are the voltages stepped up or down?: A transformer is a device that can be used to increase voltage and decrease current (or vice versa). It uses AC power and is based on Faraday's law of induction (mutual induction). A transformer is made up of two coils, each with a different number of turns, linked magnetically through a soft iron core. The magnetic flux from one coil links the other through the core. When the flux in one coil changes, the flux passing through the other will change, inducing a voltage (emf) in the second coil. The coil connected to the AC power source is known as the primary coil (number of turns Np), while the coil in which voltage is induced is known as the secondary coil (number of turns Ns). If the primary coil sets up a changing flux, the voltage in the secondary coil depends on the number of turns in the secondary. The transformer is assumed to be ideal in which the resistance of the coils is negligible and all the flux in the core links both primary and secondary windings. There will be no energy loss in an ideal transformer.

Q: i think transformers: The simpsons by far! Transformers had too many effects,it got old after a while.

Q: Actually both amplifies the input voltage. A step up transformer amplifies the input voltage and a transistor also amplifies. So what is the differece????: Easy. A transistor is a semi conductor that can essentially function as an on-ff switch. On certain configurations, you can use a transistor circuit with the right driving voltages to function as an amplifier/ Where as a transformer, is an active lumped circuit element which composed of wound coils, and ferromagnetic elements as a core which steps up or down the voltage of an electrical current by mutual induction. The principles behind both are VERY different, both in function, understanding and operation. Hope I helped some :)

Q: A transformer rises the voltage in proportion of 1 to 10. If the power in the primary coil is 100 watts, we should expect a power of ____ watts in the secondary coil. a) 10b) 100c) 1,000: As that of primary:100.

Q: Halo4 - love the series, Halo 3 is my favorite, hated Reach. not sure if Halo 4 is more like halo3 or more like reach, will not buy if abilities are includedBlack Ops 2 - BLOPS was my favorite shooter, I will probably get this unless they lower the health to MW2/MW3 standards and they don't fix SMGsTransformers FOC - War for Cybertron was one of the best games I've ever played, but they made Dark of the Moon which was a really bad shooter, and I'm not sure if FOC will be bad as wellWhat would you suggest?: I would say BLOPS 2 because I have not played any of the other games prequels. That is because I play on ps3 so I am unable to play Halo and Transformers never interested me. Plus I know if there is an error in BLOPS 2 Treyarch will fix it to the best of their abilities unlike IW's take on development which is we have your money already so we don't care.

Q: I want to know how much the current will increase. But the transformers i'm looking at VCT VT10000 - 10,000 Watts Heavy Duty Continuous Use 110V / 220V / 240V Step Up / Step Down Voltage Transformer or 15,000 Watt Step Up and Step Down Voltage TransformerI figure the whats is the total possible power and if you divide the power by the intial voltage you get the current and if you divide by the out put voltage you get the final current? but what if you input doesn't equal 15000 watts or whatever the power is?: the power output of the transformer depends upon transformer ratio. transformer ratiosecondary voltage/primary voltageOR no. of secondary turns/no. of primary turns in this case, transformer ratio220/1102. and transformer's capacity is denoted in KVA or VA. also, a transformer can only transform power(increasing voltage levels while decreasing current level and, vice versa), but it can't change the amount of power. the power of a transformer will remain constant for any input. hence, if the input voltage decreases, the input current increases, making the power a constant. for a step up, output or secondary voltage will increase, magnitude depending upon the transformer ratio.

Q: I mean i want to watch transformers 3, do i have to watch 1 and 2 to enjoy the film ?: Yes, Transformers: Dark of the Moon follows Transformers and Transformers: Revenge of the Fallen. I don't think the story's so complex that you won't be able to follow it, but I would recommend watching the first two films if you have the time.

Q: I have a transformer 12v and 12v need to reduce these further to be able to grow or shrink the rotational speed electromotor.Which device or component would be used to reduce the speed of electromotor?I making a mini escalators: A transformer has AC output, so first get DC, which needs a rectifier and capacitor. Following this is a voltage regulator using an LM317 (adjustable 3 terminal regulator). This can delivers ~1 amp. You should know what maximum current your motor draws under load. The first link is an example for 1.25V-15 V with an 18V transformer. Use a 12V transformer, and a 1000 ohm potentiometer as a variable resistor instead of 2000 ohms (R2). This will give voltages from 1.25V to 7.0V DC. Use the formula to calculate other resistors for a different voltage. Get the LM317 in a TO220 package, and you will need a heat sink, at least as big as in the picture. You can probably find a kit of parts for this in an electronics shop.

Q: I live at an apartment complex and I was just returning from work when the entire complex went completely dark. All 12 buildings went offline at the same time, along with the outside lights and the covered parking lights. Since each building has its own transformer, shouldn't they be independent of the others? Why did all 12 buildings and the outside lighting go out together? Are they all on one line or something?: Are they all on one line or something? Yes. All the transformers likely get power from the same seller. If the transformer are the leaves of a tree then a branch supporting all of them was cut or damaged.

Q: Does the production transformer require 3C certification? Does the country have any specific requirements?: In general, the production of power transformers do not require 3C certification. The state does not have specific requirements, but if you want to tender, is certainly qualified, the most important is: the state authority of the type of test report (often: National Transformer Quality Supervision and Testing Center (Shenyang)) and model registration Certificate, then ISO9001
