Q: For most consumer electronics, there'll be a transformer within the adaptor that converts AC to DC. For the basic of the transformer, I'll just assume it's just a primary coil running the secondary coil.So, the primary coil keeps on running at full power, as long as electricity is needed for the appliances. Does this mean that even on standby mode, the adaptor still takes in full power from the power socket?: primary coil keeps on running at full power incorrect. wrong. The secondary has a load, and that load draws current, which may be anywhere from zero up to the maximum load rating of the transformer, say 10 amps. Depending on the turns ratio (say it is 10:1), that amount of current is supplied by the primary, multiplied by or divided by the turns ratio. In our example, this would be 1/10 th the secondary. So if the secondary drew 10 amps, the primary would draw 1 amp from the wall socket. If the secondary drew 1 amp, the primary would draw 0.1 amp. And 0 amps would cause the primary to draw 0 amps from the wall socket (for an ideal transformer. Real world, there is a small current being drawn, how small depends on how good a transfomer it is) edit, for your additional details. I determined that it keeps on running at full blast based on the idea that it's a separate circuit. wrong Since it is always creating magnetic field (which it must, since it's a coil), and creating even when no ones taps on it, it must run at full blast at all times. wrong, with no load, the magnetic field is much weaker. Unless there's a way the primary circuit automatically knows nobody is tapping on it, it must be constantly making magnetic field at full blast. wrong.

Q: Rules for the operation of cooling devices for oil - cooled transformers: C, work or auxiliary cooler failure after removal, should be automatically put into the standby cooler; ?D, strong oil circulation cooling transformer operation, must be put into the cooler, no load and light load should not put too much cooler (no-load state to allow short-term cast). All the load into the corresponding number of coolers should be in accordance with the provisions of the manufacturer, according to the temperature and load switching cooler automatic device should be kept normal.

Q: i have just pulled out the flayback transformer from a tv there are many pins at the bottom and 3 wires at the top. i just want to make some good sparks. one wire is orange, one red and the other red with a sucker cap on the end. can i plug the transformer straight into the wall socket. i hear it needs a saw tooth voltage, is this already built in. please help i just want some good sparks.: A 'flyback' transformer won't do anything but blow the breaker if you plug it into the wall. They're designed to run at 15,750 Hz. and yes, they do couple a 'sawtooth' waveform out to the horizontal deflection coils of the 'yoke' around the base of the CRT which deflect the electron beam to produce an image. If you want some -great- sparks, go out on the 'net and look ou plans for a 'Tesla Coil'. I've built a couple of those that would draw an arc several inches long. And since they're very low-current (on the secondary side) they're quite safe to play with. HTH, Doug

Q: Hello friendsi need transformer for my project (regulated power supply) i need 220 50hz ac input and 3 volt 50hz out put ac voltage is this possible.what is wattage of that rating transformer?thanks a lot: not enough information wattage is determined by the load demand and the efficiency of the transformer all we can tell for what you provided would be the step down windings turn ratios what is being powered on the 3 vac side of your project?

Q: I am looking into purchasing a counter top coffee roaster that requires a 30 Amp 120 outlet; manufacturer says it uses about 21A.The only plug/circuit that can handle this load at this time is a 240 V outlet. We have a gas stove and we are not currently using the circuit.Does anyone know of a manufacturer that makes a external/freestanding step down (240 to 120) voltage transformer / regulator that I can plug into a grounded (North American) 220V outlet ? Note: a) I don't need it to be variable, just a fixed 240V to 120V is perfect. b)It would also need some sort of internal voltage regulation/ stabilization as erratic voltages would affect the (coffee) roast.: If each leg of the 240v circuit is 30 amps, you won't need a transformer at all. There are travel kits for going to foreign countries that have a variety of adapters for plugging into 240V outlets that only use one leg of the circuit, which is 120v. Find the adapter that fits your outlet, and you will be up and running! DO NOT TRY TO MAKE SUCH AN ADAPTER YOURSELF UNLESS YOU HAVE A DEGREE IN ELECTRICTY/ELECTRONICS! Using a transformer involves balancing the load, getting a transformer that is rated for the current, a lot of worms in that can. There are also adapters available to stabilize the current, they are available wherever compurers are sold.

Q: What is the unit of the transformer?: KVA instead of KW? VA or KVA is the apparent power, AC line used, also known as the capacity, that is, voltage and current rms product, the unit ... but will affect the load design of the transformer, so use VA or KVA to calculate more accurate. And W or KW is our usual habit of the law, written formal.

Q: i wish to construct a transformer with 220/120v,60hz,5watt,plz help me: Please don't! By the time you buy the special core material, the 2 types of copper wire, a good house content and life insurance for yourself, you can buy a finished and safe one from Maplin (if you are in the UK) for Pds.15.99 and that is a 45 Watt type. And finally, you say you want 60 Hz ? Then you also need 60Hz at the input, because a transformer doesn't change from 50Hz to 60Hz. Still want to know how it works?

Q: hello thank you for reading this question, i have a iron cored dc-ac transformer (relies on interrupter to constantly break circuit to induce induction in secondary coil) a brief and crude diagram can be found: If I understand correctly, you want to turn an old transformer into an electromagnet, and you want to use both windings in order to get the strongest possible field. First of all, you are going to need to modify the core: It needs a gap. In a perfect transformer, the lines of magnetic force would be entirely confined to the core.

Q: I broke a small transformer that I found inside of my DVD player, and I would like to have one (not for the DVD player, just separately) I would like the transformer to take in low voltage, such as a few AA or AAA batteries, and I want it to scale that up. Does anyone know where I can get one? If not are there any instructions on how to make an effective yet inexpensive one?Thanks in advance!: A transformer cannot step up or step down DC power. (All batteries are DC). That is part of their nature. A basic transformer is nothing more than two (or more) inductor coils in close proximity, often with a steel core to help with the magnetic fields. All inductor coils are basically a coil of conducting wire, most often copper.

Q: What is the transformer absorption ratio (R60 / R15): Generally, the absorption ratio should be greater than or equal to 1.3 as the absorption ratio is acceptable.
