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

Will 120 volt equipment work on a 110 volt transformer?
Yes.
What is 4160 Volt electrical wire insulation rated for?
You can use an insulation rating 5000 volt to run 4160 volt supply.
How Convert 200 volt to 230 volt?
If a precision voltage is needed from 200 to 230 an auto transformer could be used. If the load is a 230 volt motor to be operated on 200 then add 15% to the nameplate full load amperage for the calculation for overload protection.
500 watts is how many amps?
The same number as 250 oranges is apples. A watt is a volt times an ampere.
Transformers are rated in what?
Transformers are rated in KVA. (this is because the transformer is Unity power factor device i.e.. PF = 1)AnswerThe selection of a transformer is determined by the apparent power of the load, expressed in volt amperes(V.A), the load current, and the line voltage of the supply. The transformer must be able to satisfy these requirements.Transformers are not 'unity power factor' devices, which is precisely why their capacity is expressed in volt amperes, rather than in watts.
What is the current carrying of an 1000kVA transformer?
You cannot answer this question without knowing the rated secondary voltage. Once you know this, divided the voltage into the volt ampere rating.
What is mean KVA Rating of transformer?
copper loss is directly propostional to I (AMPERE) and iron loss directly propostional to V (VOLTAGE) then total losses is equal to volt ampere hence the rating of transformer in KVA. SULTAN
Volt ohm ampere and watts are terms associated with what?
ohm is used to measure resistance of electric current. Ampere is used to measure electric current. volt is used to measure voltage.
What is the same on both sides of any transformer?
frequency. KVA is also same in both side of a transformer!!! KVA means Kilo Volt Ampere.
The unit to measure current is the volt?
The unit of current is the ampere. The unit of potential difference, or electromagnetic force is the volt.
Why is the rating of transformer in kVA?
kVA is essentially power rating (capacity) of a transformer. Since power is equal P=I*V, so P=kV*A, with I measure in Amps or denoted as A.AnswerA transformer's iron losses depend on the magnitude of the flux which, in turn, is proportional to voltage, while its copper losses depend on the winding currents. As both iron and copper losses contribute to the maximum operating temperature of the transformer, it follows that a transformer must be rated in terms of voltage and current. In alternating current systems, the product of voltage and current is apparent power, expressed in volt amperes.As a transformer's secondary voltage is kept approximately constant, it is its 'volt ampere' rating that determines its maximum (secondary) load current.Expressing a transformer's rating in watts (i.e. true power) would be completely meaningless because, with a highly-reactive load, it will be supplying practically zero watts while still having to supply its rated current.
What volts ohm ampere and watts are terms associated with this?
ohm is used to measure resistance of electric current. Ampere is used to measure electric current. volt is used to measure voltage.
The nec requires that continuous load calculations be increased by an additional percent volt-ampere rating?

What is the full load loss of a 630 kilo volt ampere and primary voltage is 11000 VOLT and secondary voltage is 440 VOLT of a distribution transformer?
That type of transformer normally has about 99% efficiency so the full-load loss would be 1% or 6 kW.
How can you measure the power rating of a 1.5 kg step down transformer that converts 240 volts to 112 volts?
You cannot 'measure' the rated power (or, more accurately, 'apparent power') rating of a transformer. You can, though, calculate this value, which is the product of the rated secondary voltage and the rated secondary current, and is expressed in volt amperes.This information can be found on the transformer's nameplate data label.
Why transformer rating is in kva?
major losses in the transformer in the volt-ampers.AnswerA transformer's iron losses depend on the magnitude of the flux which, in turn, is proportional to voltage, while its copper losses depend on the winding currents. As both iron and copper losses contribute to the maximum operating temperature of the transformer, it follows that a transformer must be rated in terms of voltage and current. In alternating current systems, the product of voltage and current is apparent power, expressed in volt amperes.As a transformer's secondary voltage is kept approximately constant, it is its 'volt ampere' rating that determines its maximum (secondary) load current.Expressing a transformer's rating in watts (i.e. true power) would be completely meaningless because, with a highly-reactive load, it will be supplying practically zero watts while still possibly having to supply its rated current.
What is the amp rating of 100va transformer?
The amp rating for a 100VA transformer will vary depending on the actual voltage of the transformer. Transformers have both a primary and a secondary voltage.
