The purpose of a transformer is to transform one voltage to another voltage. This can be in the configuration of stepping up the voltage or stepping down the voltage . The load is what establishes what the current from the transformer is going to be.
Yes, if you use a 240 volt to 480 volt step up 15 KVA transformer. This will give you 30 amps usable at 480 volts.
To answer this question a voltage must be given. 25 amps drawn by a bulb seem to be on the high side.
A panel does not generate any current, the generating happens at the power plant. A 280 watt panel on a 120 v supply can supply up to 2.3 amps.
The amperage rating of the transformer in a 12V power supply cannot be changed. The size of the copper windings determine the power load (amps) it can handle and the point where the lead is tapped off of the windings determine the voltage. The only way to increase the amperage would be to tap closer to the core which would lower the voltage.If you need more amps you have to have a heavier transformer.
If you have 100 amp wire, you can use it for a 60 amp circuit, or for any circuit of 100 amps or less. But if you have a 60 amp circuit, 60 amp wire is thinner and cheaper than 100 amp wire.
If the load you are connecting to the transformer uses 1.5 amps or less, yes.
2.083 amps
It generates 25 Amps.
No because the current rating of the transformer is a maximum allowable current. If the computer still takes 3.42 amps it will be OK provided the new transformer supplies the correct voltage.
Yes, as long as the load attached to the wire does not exceed 0.022 amps.
Amps * Volts = Watts Amps * 12 = 600 600/12 = Amps = 50 amps You would need a reserve capacity, so I'd go somewhere between 60 or 100 Amp rated transformer. Transformers are rated in volt-amps which is usually calculated the same as watts. But the term "watts" technically does not apply to transformers. So you need a 600 volt-amp transformer or, as Redbeard has suggested, you need an 800 or 1000 volt-amp transformer. That's a lot of amps for a 12 volt system so I recommend you double check your requirements. You will need a #2 gauge wire if your requirements are correct.
you get a transformer...
There are many ways but never can you multiply the power. <<>> A current transformer is specifically designed, by amp turns, to only output 5 amps. Meters that are connected to CT's have a full range deflection (scale) of 5 amps. To do what you are asking seems pointless as there are no meters with 10 amp full scale deflection.
Your transformer should have a namplate on it that states how many amps or fractions of amps it can produce. You would then multiply that number by your secondary voltage to get your VA rating. sec. voltage 12v X .05 amp = 12 X .05= .6va
Yes you could use a 20 kva transformer in a home. Stymied as to why it would be done though. You would need at least a 100 amp service to the home to energize the transformer. Primary side of the transformer would draw 83 amps at 240 volts. If the question was to supply the home, again yes. It would be 100 amp service equipment that the transformer would feed into.
A type of current transformer used as a metering device. You clamp the tong around a wire and it will tell you how many amps are flowing though it.
The maximum current output of a CT is 5 amps. Connected to a meter this will be full scale. What ever the ratio of the CT will dictate the scale face on the meter. A 500 amp CT's output will be 5 amps at 500 amps on the buss. 250 amps on the buss, the CT will output 2.5 amp or half scale on the meter face.
