FAQ

I understand that transformers used to lower voltage for AC power transmission, simultaneously change both the voltage and current, but if such a transformer were in used in say a 12 volt dc power adapter that plugged into the wall outlet, then it would be counterproductive if the voltage lowering transformer upped the current as too much power would be dissipated, and a current boost would be unwanted, right? Same with transformer for PC power supplies. They must lower voltage without upping the current, right? Thanks a lot.

transformers work only when the input is AC not DC after the out put is obtained then the AC is converted to DC by rectifier. however the process of change would have already taken place in the main sequence whatsoever the rectifier does. in small amounts of current the change would be negligible

around the house. Im looking for a step up transformer to handle 1.5VAC-18VAC with a ratio of 1:10 or 1:20. Which household objects would contain this??

Depends on your house. Unless you collect electronic parts, the odds are about zero. Even inside appliances and such, the only tranformers are stepdown from 120 to about 12 volts. .

i have been looking at transformers and i wanted to know a few things. will they do dc current? do they just add x amount of volts or do they multiply by x or just change to x? also there is a sort of container that goes around them is that carbon???? it goes all the way around and then through

the average transformer you see on a power line, is takin a higher voltage and is distrubing down to what your house can handle which is usually 200amps. A transformer is nothing more than copper coils wrapped around carbon metal. And on the side of the transformer there is a voltage input and output tag. Transformer are huge and small. I work with them everyday.

Does anyone have any knowledge or experience with what happens if you try to run two different power supply transformers from the same AC line input. Can you do that? I have one transformer with a primary DC resistance of 28 ohms. I have a second transformer with a primary DC resistance of 265 ohms. I want to run these two transformers from the same AC power cord input. I tried connecting their primaries in series across the AC cord input, and the resulting secondary outputs from both transformers were lower than expected for a no-load condition. I am a little concerned about trying to connect the two transformer primaries in parallel.Any ideas?

you can connect as many in parallel as you want, if they are all rated at 120 volts AC input. After all, all of the appliances, lights, etc in your house are all connected in parallel, and many of these have transformers. That is what parallel connection is. They all get the same voltage, and they are all independent of each other. .

Transformer secondary side is high pressure or primary side is high pressure

Transformer can be divided into two types of step-up transformer and step-down transformer, the primary side of the transformer is the voltage input, the secondary side is the output. Step-up transformer is the secondary side voltage greater than the primary side, step-down transformer is the secondary side voltage is less than the primary voltage.

I want to buy the original transformers, but i see there are different parts like more than meets the eye orarmada? idk, please help me. :)

You want the one that's just Transformers. The DVD sets were released from Rhino and have silverish-metallic looking boxes. Forget the later anime series Armada or Energon.

I have a standard transformer with 7 wires:2 black2 red2 yellow1 red/yellow stripedWhat connections do these wires correspond to?That is, which should connect internally to the primary coil, the secondary coil, and coil-taps (based on the number of wires, I assume that the secondary coil is tapped).I must determine this in order to connect the wires (externally) appropriately.Any help is greatly appreciated!

Transformer Wire Colors

hi guys can any of you give me advice on wot i need 2do on removing and replacing a faulty line output transformer on a rear veiw projection tv as i have the part and the local tv shop wont fix it 4 me.wot would be the best way to discharge the power from it first and could i jus cut the 2 wires on the old 1 and use connector blocks to connect the new 1 in would this be ok to do or do it need to soilder connected on?. and is there any adjustments that would need to be done to the set when i have it installed be4 i turn it on any help much appreicated

If you have an identical replacement transformer there shouldn't be a need to adjust anything to start. As to cutting wires to remove the old transformer to replace the new one, I suggest you make yourself a chart of any color coding of the wires or tagging them so there is no error as to what to connect to what on the new transformer. I personally would replace the transformer as the manufacturer installed the original one. As for discharging, use a 10K ohm resistor with one side to ground and the other side of the resistor to the components you want to discharge. I don't advise just grounding direct. Good luck and be careful.
