What else can I help you with?
Rating of transformer?
It's the apparent power (VA) it can deal with.
What does 40 VA mean in a transformer?
In a transformer, 40 VA refers to the apparent power rating of the transformer. VA stands for volt-ampere, which is a unit used to measure apparent power in an electrical circuit. A transformer with a rating of 40 VA can handle a maximum apparent power of 40 volt-amperes, which is the product of the voltage and current it can handle. This rating is important for determining the capacity and suitability of the transformer for specific applications.
What is current carrying for 2200kVA transformer?
Presumably you are asking about the rated secondary current of a transformer rated at 2200 kV.A?This depends on the rated secondary voltage. You divide the rated apparent power of the transformer by the rated secondary voltage.Of course, the actual current depends on the load.
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
How do you calculate current capacity of transformer?
The secondary winding's current rating is the rated apparent power of the transformer (expressed in volt amperes) divided by its voltage rating (expressed in volts). This applies to both step down, and step up, transformers.

How many watts does a 22VA transformer have?
A 22VA transformer has a power rating of 22 watts. VA (volt-ampere) is a unit used to measure the apparent power in an electrical circuit.
What is a current of transformers?
The current rating of transformers vary widely as well as the types (step-down, etc.....). So depending on the use, the primary power, and the secondary power, the amp load will change. More in general current is amps, if your transformer has say 1Kva on it then that tells you the apparent power the transformer can handle. As a side note a lot of transformers are rated in VA or KVA and that is a combination of volts and amps (apparent power).
What is meaning of Transformer stability and sensitivity?
What is meaning of Transformer sensitivity?

Presumably you are asking about the rated secondary current of a transformer rated at 2200 kV.A?This depends on the rated secondary voltage. You divide the rated apparent power of the transformer by the rated secondary voltage.Of course, the actual current depends on the load.
Why transformer rating is called kva not kw?
Transformers are rated in KVA because that is a more accurate way to measure their capacity requirements. KWH is apparent power, while KVA is true power, and the ratio between them is power factor. The power factor is a function of the load, and not the transformer, so a poor power factor would make KWA look less to the transformer while, in fact, the true power, if not met by the transformer, could overload the transformer.
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.
What is meant by the term ideal transformer?
ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal transformer
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What is the current of a 45 kva transformer?
Presumably, you are asking what is the rated secondary current for a 45 kV.A (not 'kva') transformer? The answer depends on its rated secondary voltage. To obtain the rated secondary current, you divide the (apparent) power rating by its secondary rated voltage.
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
